Section 3 Age of Legal Capacity (Scotland) Act 1991 allows for prejudicial transactions to be set aside. What is a โ€œprejudicial transactionโ€ in Scotland? Who can apply, when, and what orders can the court make under Section 3 of the Age of Legal Capacity (Scotland) Act 1991?

Where Section 3 fits in

Section 3 provides a safety-net for young people who entered a legally binding transaction between ages 16 and 18. Even though 16โ€“17 year-olds generally have capacity (see your Section 1 guide), the court can still set aside certain deals if they are prejudicial.

Who can apply โ€” and by when?

  • The applicant: the person who made the transaction, if they are under 21 at the time of applying.
  • Deadline: application must be before the applicant turns 21.
  • If the applicant has died or is insolvent: the executor, trustee in bankruptcy, trustee under a trust deed for creditors or (historically) curator bonis may apply on their behalf, but still before the 21st birthday would have occurred.

Note: the curator bonis office is now obsolete in practice following the Adults with Incapacity (Scotland) Act 2000 and later reforms; modern routes include guardianship/judicial factor.

What is a โ€œprejudicial transactionโ€?

A transaction is โ€œprejudicialโ€ only if both tests are met:

  1. Prudence test: An adult, exercising reasonable prudence, would not have entered into that transaction in the applicantโ€™s circumstances at the time; and
  2. Harm test: the transaction has caused or is likely to cause substantial prejudice to the applicant.

This is a fact-sensitive assessment: price/terms, pressure, information asymmetry, complexity, alternatives, and the applicantโ€™s circumstances at the time all matter.

Statutory exclusions – when Section 3 does not apply

You cannot use Section 3 to set aside:

  • using will-making powers (testamentary acts) or exercising a power of appointment;
  • consenting to adoption of the applicant;
  • bringing/defending civil proceedings;
  • consenting to medical/dental treatment;
  • transactions done in the course of the applicantโ€™s trade, business, or profession;
  • transactions where the other party was induced by the applicantโ€™s fraud (e.g., lying about age);
  • transactions ratified by the applicant after turning 18 with knowledge they could be challenged under Section 3;
  • transactions ratified by the court under Section 4.

(For the medical/adoption/solicitor exceptions that begin at age 12 or apply under 16, see your Section 2 guide.)

Procedure and court powers

  • How to apply:
    • raise an action in the Court of Session or sheriff court, or
    • make an incidental application in ongoing proceedings.
  • What the court can do:
    • make an order setting aside the transaction, and
    • make any further order needed to adjust the partiesโ€™ rights (e.g., repayment/restoration).

Practical examples (illustrative)

  • High-cost finance at 17: A 36-month, high-interest loan sold on aggressive terms may be set aside if a prudent adult wouldnโ€™t have agreed in the same circumstances, and the deal substantially prejudices the young person.
  • Cosmetic procedure at 16 with informed consent: Not challengeable under Section 3 if it falls within medical consent (which Section 3(3)(e) excludes).

Evidence and strategy tips

  • Timing: Miss the 21st birthday and the Section 3 remedy is gone.
  • Prove both limbs: gather pricing comparisons, expert opinion on fairness, sales scripts, records of pressure/misrepresentation, and the applicantโ€™s personal/financial context at the time.
  • Consider alternatives: consumer protection routes (misrepresentation, unfair terms/credit), but Section 3 is often the cleanest path for 16โ€“17 transactions.

How Section 3 interacts with Sections 1 & 2

  • Section 1 gives full capacity at over 16yo; Section 3 recognises some deals made at 16โ€“17 may still be unfair enough to unwind.
  • Section 2 carves out under-16 exceptions (everyday deals, wills at 12, medical consent, instructing a solicitor, etc.). Those specific areas are excluded from Section 3 challenges.

FAQs

Is a bad bargain enough?
Not by itself. You must show both that a prudent adult wouldnโ€™t have entered it in those circumstances and that it caused/likely causes substantial prejudice.

Can I challenge after turning 21?
No โ€” the statute imposes a hard stop at 21 (with the representative-applicant options only up to the same date).

What if I ratified the deal at 18?
If you knowingly ratified after 18, Section 3 is not available.

Why does the Act mention โ€œcurator bonisโ€?
Itโ€™s historic language. In practice, curators bonis are no longer appointed; the Adults with Incapacity (Scotland) Act 2000 and later reforms replaced that role with modern mechanisms.
