Satisfaction and Performance in UK Wills: Equitable Doctrines Explained
Updated 18 May 2026 · 7 min read · England & Wales
When a testator’s will and their lifetime dealings overlap — a cash legacy and a subsequent cash gift to the same child, or a covenant to leave property followed by a lifetime conveyance — equity steps in with a pair of rebuttable presumptions: satisfaction and performance. Understanding these doctrines matters both for will drafters (who must exclude them expressly) and for executors (who must consider them before distributing).
What Are the Doctrines of Satisfaction and Performance?
Satisfaction and performance are equitable presumptions about a testator’s intention that arise where a will gift and a lifetime dealing appear to overlap. They are not rules of law but rebuttable presumptions: any evidence of a contrary intention will displace them.
Both doctrines rest on the same equitable foundation: equity leans against double portions and presumes against double payment. If equity did not intervene, a beneficiary could receive both a will legacy and a lifetime gift serving the same purpose — obtaining a windfall the testator almost certainly never intended.
- Satisfaction arises where a later act is presumed to replace or discharge an earlier obligation (the will legacy or the debt).
- Performance arises where a later act is presumed to fulfil an earlier covenant or promise, even if the later act takes a slightly different form.
Both doctrines are creatures of equity operating in England and Wales. They have no direct statutory basis and survive as part of the general equitable jurisdiction. Modern will drafting practice routinely excludes them with express language.
Satisfaction of a Legacy by a Portion (The Double Portions Rule)
The most practically significant form of satisfaction is the double portions rule. Where a parent (or person in loco parentis) makes a will giving a cash legacy to a child, and subsequently makes a lifetime gift of a similar nature and comparable amount to the same child, equity presumes the lifetime gift was intended to satisfy — that is, replace — the will legacy in whole or in part. The child cannot take both.
Four requirements must all be satisfied:
- Parent-child or in loco parentis relationship. The testator must be the child’s parent or must have assumed the obligations of a parent (such as a guardian or step-parent who has taken on full parental responsibility). The rule does not extend to aunts, uncles, friends, or employers. (Powys v Mansfield [1836].)
- Same nature. The portion must be of the same nature as the legacy. If the legacy is a cash sum and the lifetime gift is cash, the rule can apply. If the legacy is a cash sum but the lifetime gift is land (or vice versa), the dissimilarity of nature rebuts the presumption. (Re Lowe’s Will Trusts [1973].)
- Will must predate the lifetime gift. The legacy must have been given in a will made before the lifetime gift was made. If the will postdates the lifetime gift, equity infers that the testator had the lifetime gift in mind when writing the will and intended to give an additional benefit — the presumption does not arise.
- Portion must equal or exceed the legacy (for full satisfaction). Where the lifetime gift is smaller than the legacy, partial satisfaction may reduce (but not extinguish) the legacy. Where the lifetime gift equals or exceeds the legacy, the legacy is fully satisfied and cannot be claimed.
Example: a will made in 2020 gives a daughter £30,000. In 2023 the parent makes a cash gift of £30,000 to the same daughter. Equity presumes the 2023 gift satisfied the legacy. The daughter takes the £30,000 lifetime gift but cannot also claim £30,000 under the will.
Satisfaction of a Legacy by a Legacy
A second, weaker form of satisfaction arises where a testator makes two separate legacy gifts to the same person — either in two different wills or in two different clauses of the same will. Equity may presume the later gift satisfies the earlier, so the legatee takes only one.
This presumption is considerably weaker than the double portions rule. It will be rebutted if:
- The two gifts are of different amounts or different types of property.
- The gifts are in the same will and both are clearly visible to the testator.
- There is any evidence of separate intention — for example, gifts made in respect of different relationships or different services.
In practice, a modern well-drawn will listing all intended gifts expressly, and including a declaration against satisfaction, will prevent this presumption from arising.
Satisfaction of a Debt by a Legacy
Where a testator owed money to a person (the creditor) and left a legacy in their will to that same creditor, equity presumes that the legacy was intended to pay off (satisfy) the debt. The creditor may take the legacy but cannot also sue the estate to recover the debt.
Requirements under Re Horlock [1895] and related authorities:
- The legacy must be equal to or greater than the debt. If the legacy is less than the debt, the presumption does not fully apply — the creditor may take the legacy and pursue the shortfall as a debt.
- The legacy must be of the same or greater benefit as the debt. A legacy of land cannot satisfy a debt of money of equivalent value unless both parties would agree it is equivalent.
This form of satisfaction is the most easily rebutted. Any evidence that the legacy was intended as a separate and additional benefit — for example, that it was left in recognition of services, or that the testator maintained the creditor relationship in correspondence after writing the will — defeats the presumption entirely. In modern practice, executors should check whether the testator was indebted to any legatee before distributing.
The Doctrine of Performance
Performance is the mirror image of satisfaction. Where a person has entered into a covenant — a binding legal promise — to do something (for example, to settle property on children by will), and instead performs a different but equivalent act during their lifetime (for example, transfers the same property as a lifetime gift), equity presumes the lifetime act was intended as performance of the covenant.
The effect is that the covenantee (the person entitled under the covenant) cannot take both: they cannot rely on the covenant and also enjoy the lifetime gift. Equity treats the lifetime act as full or partial performance of what was promised.
Re Sowden [1836] illustrates the doctrine: a person covenanted to leave land to children and then during their lifetime conveyed that same land to the children outright. Equity held the conveyance was performance of the covenant — the children could not also sue on the covenant for a further transfer.
Performance requires that the later act be of the same or analogous character to the covenanted act. If the covenant was to settle £10,000 on children and the testator instead gave unrelated shares of a different value, performance would not be presumed. The closer the later act mirrors the covenant in nature and value, the stronger the presumption.
How to Avoid These Doctrines in Will Drafting
Modern will drafting practice avoids problems with satisfaction and performance through express language and good record-keeping:
- Include an express exclusion clause. The will should state, for each specific legacy (or globally in a general clause): “Any legacy given by this will is free of any equity of satisfaction and is intended to be in addition to, and not in satisfaction of, any lifetime gift previously or subsequently made by me to the same beneficiary.” This single clause removes the entire problem.
- Keep records of gifts and their purpose. A file note or letter of wishes stating whether a lifetime gift was an advancement (intended to be brought into account) or a purely additional outright gift is strong rebuttal evidence. While a letter of wishes is not legally binding, it is highly persuasive evidentially.
- Review the will after significant lifetime gifts. If a testator makes a substantial lifetime gift to a will beneficiary, the will should be reviewed to confirm the legacy remains appropriate in amount. If the testator intends the legacy to remain in full, the will should be updated (or a codicil added) containing a fresh express exclusion.
- State clearly whether lifetime gifts are advancements. Advancements (loans or gifts expected to be counted against future inheritance) are different from outright gifts. If a lifetime gift is an advancement, say so in writing. If it is purely additional, say so. Ambiguity is what equity fills with a presumption.
Practical Implications for Executors
An executor’s duty is to administer the estate correctly in accordance with the will and applicable law. Before distributing any legacy, an executor must consider:
- Did the testator make any lifetime gifts to a legatee under the will? If so, do those gifts satisfy the requirements for the double portions rule (parent-child relationship, same nature, will predating the gift, comparable amount)?
- Was the testator indebted to any legatee? If so, does the legacy equal or exceed the debt? If satisfaction of a debt by legacy might apply, the executor must not allow the creditor both the legacy and the debt claim.
- Did the testator make any covenants to benefit the same person that might have been performed by a lifetime act?
An executor who distributes without considering whether satisfaction applies, and who allows a legatee to take both a legacy and a lifetime portion, may be exposed to a devastavit claim — personal liability for loss caused to the estate by breach of duty. Where there is any doubt, the executor should take legal advice and, if appropriate, take a form of indemnity from the legatee before distributing.
Comparison: Satisfaction, Performance, and Hotchpot
| Feature | Satisfaction | Performance | Hotchpot |
|---|---|---|---|
| Trigger | Later lifetime gift or debt payment overlaps with earlier will legacy | Later act equivalent to earlier covenant; equity treats later act as fulfilling the covenant | Lifetime advancement by parent; child shares in estate on intestacy |
| Parties | Parent/in loco parentis and child (double portions); any testator and creditor (debt) | Covenantor and covenantee; commonly parent and child | Parent and child only; applies on intestacy |
| Effect | Legacy reduced or extinguished; legatee cannot take both legacy and lifetime gift | Covenant treated as discharged; covenantee cannot enforce covenant and keep lifetime benefit | Advancement brought into account before sharing in residue on intestacy |
| How to exclude | Express clause in will stating legacy is additional to and not in satisfaction of any lifetime gift | Express statement that lifetime act is separate from and not in performance of any covenant; include in deed of gift | Write a will (hotchpot does not apply to testate estates in the same way); or state in deed of gift that it is not an advancement |
Frequently asked questions
What is the doctrine of satisfaction in English law?
The doctrine of satisfaction is an equitable presumption that where a testator has made a will gift to a person and subsequently makes a lifetime dealing with the same person (such as a lifetime cash gift or the payment of a debt), equity presumes that the lifetime act was intended to satisfy — that is, discharge or replace — the will gift in whole or in part. The doctrine is rooted in the equitable maxim that 'equity leans against double portions' and the broader principle that equity presumes against double payment. Satisfaction is a rebuttable presumption, not a rule of law: any evidence of a contrary intention — in the will, in a letter of wishes, or in the surrounding circumstances — will rebut it and allow the beneficiary to take both the legacy and the lifetime benefit. The doctrine covers three main situations: satisfaction of a legacy by a portion (lifetime gift to a child), satisfaction of a legacy by a legacy (two overlapping gifts), and satisfaction of a debt by a legacy.
When does the double portions rule apply?
The double portions rule (satisfaction of a legacy by a portion) applies when all four of the following conditions are met: (1) Relationship — the testator must stand in the position of a parent or person in loco parentis (someone who has assumed parental responsibility) towards the recipient. It does not apply to strangers or collateral relatives. (2) Nature — the lifetime gift (the 'portion') must be of the same nature as the will legacy. If the legacy is cash and the lifetime gift is cash, the rule can apply. If one is cash and the other is land or stock, the rule does not apply — the dissimilarity in nature rebuts the presumption (Powys v Mansfield [1836]). (3) Timing — the will legacy must predate the lifetime gift. The presumption is that the later lifetime gift was intended to replace what the will had already provided. If the will postdates the lifetime gift, the double portions rule does not apply. (4) Amount — the portion must equal or exceed the legacy, though partial satisfaction is possible where the lifetime gift is smaller than the legacy.
Can the doctrine of satisfaction be expressly excluded?
Yes — and modern will drafting practice routinely does so. The most effective way to exclude the doctrine is to include an express declaration in the will such as: 'Any legacy given by this will is given free of any equity of satisfaction and is intended to be in addition to, and not in satisfaction of, any lifetime gift previously or subsequently made by me to the same beneficiary.' Such a clause removes any ambiguity about the testator's intention and prevents the doctrine from applying regardless of the size, nature, or timing of any lifetime gift. A separate letter of wishes confirming the testator's intention — that the will legacy is in addition to a known lifetime gift — also carries evidential weight, though it is not legally binding. The doctrine can equally be rebutted by any surrounding circumstances showing that the testator did not intend the lifetime gift to displace the will legacy.
What is the doctrine of performance?
The doctrine of performance is the mirror image of satisfaction. Where a person has entered into a covenant (a binding contractual or equitable promise) to do something — typically to settle property on children or leave property by will — and instead of doing exactly what was covenanted they do something different but equivalent or similar, equity presumes that the later act was intended as performance of the earlier covenant. The leading example is Re Sowden [1836]: if a person covenanted to leave land to children by will and instead conveyed the same land to the children as a lifetime gift during their lifetime, equity would treat the lifetime conveyance as performance of the covenant — the children could not then also claim under the covenant. As with satisfaction, performance is a rebuttable presumption. Evidence that the lifetime act was intended for a different purpose, or was of a different character from what was covenanted, will rebut it.
How does satisfaction differ from the hotchpot rule?
Satisfaction and the hotchpot rule are related but distinct doctrines. The hotchpot rule (now largely abolished for intestacy by the Administration of Estates Act 1925) required a child who received a lifetime advancement from a parent to bring that advancement into account (throw it into the 'hotchpot') before sharing in the parent's estate on intestacy — ensuring equality between children. Satisfaction, by contrast, operates in the context of a will: it presumes that a lifetime portion satisfies a specific will legacy (so the child takes the lifetime gift instead of the legacy, not both). The key differences are: (1) Hotchpot applies on intestacy; satisfaction applies where there is a will. (2) Hotchpot is about equality between children sharing a residue; satisfaction is about whether a specific legatee can take both a legacy and a lifetime gift. (3) Hotchpot has been largely abolished; satisfaction remains operative as an equitable presumption, though easily rebutted in modern practice.
Does satisfaction apply where the lifetime gift is larger than the will legacy?
Where the lifetime gift (portion) is larger than or equal to the will legacy, equity presumes full satisfaction — the will legacy is entirely discharged and the legatee cannot also claim the legacy. Where the lifetime gift is smaller than the will legacy, equity may presume partial satisfaction — the legacy is reduced by the amount of the lifetime gift. For example, if a parent's will left £20,000 to a child and subsequently made a lifetime gift of £15,000 of the same nature, equity would presume partial satisfaction, reducing the legacy to £5,000. The child would receive a total of £20,000 between the two transfers (the £15,000 lifetime gift plus a £5,000 reduced legacy) rather than £35,000. As always, this is a rebuttable presumption and can be displaced by evidence that both the lifetime gift and the full legacy were separately intended.
Make sure your will says exactly what you intend
The doctrines of satisfaction and performance can override your will if it is silent on the point. WillSafe’s documents include express exclusion language so your beneficiaries receive what you intend — no more, no less.
