Wages and bank accounts are attached under different parts of the Act, with different remedies and different clocks. Getting the two apart is most of the answer.

There is a catch worth knowing early. Section 50 is about whether the arrestment is valid and how it is being operated, and can you challenge a wage arrestment you think is wrong covers the grounds themselves.

Two things, and section 50 provides both. Under section 50(1) the sheriff can declare that an arrestment is invalid or has ceased to have effect, and under section 50(3) the sheriff can determine a dispute about how it is operating.

The two routes, side by side

Neither form has a deadline attached and nothing in section 50 sets a period within which an application must be lodged. The Scottish Courts and Tribunals Service publishes the rules, and the sheriff clerk can explain the forms without giving legal advice.

The difference between them

Section 50(1) asks whether the arrestment should exist at all. Section 50(3) accepts that it exists and asks whether it is being run correctly.

A miscalculated deduction is the classic section 50(3) point, and what happens if your employer deducts the wrong amount goes through it. An arrestment that should have fallen away months ago is a section 50(1) point.

A notice of objection to a bank arrestment must be lodged within four weeks of execution, under section 73M. That window has nothing to do with an arrestment of your wages.

The bank arrestment runs on its own clock

• Funds above the protected minimum are frozen from the moment of execution.
• A notice of objection must be lodged within four weeks of execution, under section 73M.
• Frozen funds are released to the creditor automatically 14 weeks after execution, unless you sign a mandate releasing them earlier or lodge an objection.
• The protected minimum balance is £1,000, on the face of section 73F(3)(a) since 1 November 2022.

That 14-week window is the reason not to sit on the letter. Doing nothing has a default outcome, and it is the money going to the creditor.

The unduly harsh route has no deadline either

Sections 73Q and 73R let a debtor apply for release of arrested funds where the arrestment is unduly harsh to them or a dependant, and if the sheriff is satisfied of that the sheriff shall order release. What is an unduly harsh application and how do you make one sets out the test.

The application is Form 63G under rule 69E and may be made at any time while the arrestment has effect. Keep it separate from the four-week notice of objection, because they are different applications with different tests.

Yes, and this is the one real deadline in the whole subject. Section 69(4) bars any claim against the employer about a deduction more than one year after the date it was made, or ought to have been made.

What the year covers

The bar applies to a claim by the debtor and to a claim by the creditor, and it covers a deduction that was made as well as one that ought to have been made.

So a worker who spots a payroll error more than a year later has lost the route against the employer, whatever the merits. Can you get a refund if your employer over-deducted sets out where a claim goes instead.

The employer is often the wrong target anyway

Section 69(5) protects the employer for deductions made before it received intimation that the debt was paid, that the arrestment was recalled, that the estate was sequestrated, or that the creditor had abandoned it.

Where too much has been taken because nobody told payroll to stop, the money comes back from the creditor. Section 57(5) of the Debtors (Scotland) Act 1987 makes any sum paid over in excess of the debt recoverable from the creditor, with interest.

Section 57(6) goes further where the creditor failed to tell the employer to stop. The sheriff can order the creditor to pay up to twice the excess.

No. Section 46(2) of the 1987 Act abolished the old rule exempting a reasonable amount for subsistence and replaced it with the fixed bands in Schedule 2, so there is no affordability ground to argue.

This is the hardest fact in the subject

It is better heard early than discovered three months in. The unduly harsh test in sections 73Q and 73R reaches arrestments that attach funds or moveable property, which means bank and third-party arrestments, and it does not reach wages.

Where the affordability argument goes instead

A time to pay order is competent against a summary warrant, including council tax, because section 15(3)(aa) puts a summary warrant inside the definition of decree or other document. What is a time to pay order explains the application, and whether one is competent on your own facts is a question for a money adviser or the sheriff clerk.

Something specific about the arrestment’s validity or its operation. Vagueness gets nowhere, so work out which of the two routes you are on before you apply.

Points that go to validity or cessation

• The arrestment relates to a debt that is not yours, or names the wrong person.
• It has already ceased by statute, on sequestration or on the protection of a trust deed.
• A conjoined arrestment order is in force against the same employment, so a separate earnings arrestment is not competent.
• The employment it attached to has ended, so the arrestment fell with that job under section 47(2).

Points that go to operation

• The wrong table has been applied, for example weekly rates against monthly pay.
• The deduction was taken from gross rather than net earnings.
• Something has been deducted before net earnings were worked out that section 73(1) does not allow.
• More than one £1.00 administration charge has been taken for a single deduction.

Many of these get sorted without going near a court, because a clear letter with the payslips attached often fixes a payroll error faster than an application would.

Yes, in practical terms. Money already deducted before a debt solution takes effect is usually credited against the debt rather than refunded, so every week you wait is money you are unlikely to see again.

The arithmetic, not a rule

There is no deadline punishing you and there is still a cost. On weekly pay, three months of deductions is thirteen paydays gone.

Check the figures with the creditor rather than assuming either way, and ask in writing how each deduction has been applied to the balance.

The statutory moratorium is another reason to think about timing, because only one is available in any rolling 12-month period. Can a statutory moratorium stop a wage arrestment covers what it does and does not reach.

A sensible order to work in

• Get the paperwork: the arrestment schedule, your payslips, and a written statement of account from the creditor.
• Check the arithmetic against the Schedule 2 tables in force since 6 April 2025.
• Raise any error with payroll or the creditor in writing first.
• Speak to a money adviser about the routes that stop the arrestment, rather than only the ones that argue about it.

Several steps around an arrestment are time limited even though section 50 is not. These are the ones that most often matter to somebody already losing part of their pay.

The clocks, in one place

The charge for payment, and one thing that is not settled

On an ordinary court decree the position is settled. Section 90(1) of the Debtors (Scotland) Act 1987 makes a charge for payment, served and expired unpaid, a precondition of an earnings arrestment, and section 90(3) sets the period at 14 days in the United Kingdom.

On a summary warrant it is not settled. Schedule 8 to the Local Government Finance Act 1992 authorises an earnings arrestment directly and says nothing about a charge, while section 90(1) carries no summary warrant exception on its face.

No page should tell you the answer either way, so ask a money adviser or the sheriff clerk what applies on your own account. What is a charge for payment explains the document and the 14 days.

Where a charge is required, it has a life of its own. It cannot found diligence more than two years after it was served, under section 90(5) of the 1987 Act, after which a fresh one has to be served.

Not on any timescale worth planning around. Council tax is excluded from the five-year rule that clears most consumer debt and sits instead on the twenty-year long negative prescription.

What changed on 28 February 2025

The twenty years run from the date the obligation became enforceable, under the wording substituted into section 7 of the Prescription and Limitation (Scotland) Act 1973 on that date.

Enforcement does not send the clock back to the start. A relevant claim, which includes executing diligence, extends the twenty-year period until that claim is finally disposed of.

A payment or a written acknowledgement does not affect the twenty-year period at all. Section 10(1) of the 1973 Act now applies only for the purposes of sections 6 and 8A, and section 7 is not among them, so acknowledgement has no part in the twenty-year rule.

Who has to prove what

Section 13A of the 1973 Act, inserted on the same date, puts the burden on the creditor. Where a question arises about whether an obligation has been extinguished, it is presumed to have been extinguished unless the creditor proves otherwise.

The five-year rule is different and has not changed. Under section 6 a payment or a written acknowledgement still interrupts the period and sends it back to the start, which is why the advice to take advice before paying an old debt still holds for ordinary consumer debt.

Why none of that makes waiting a plan

Twenty years is a long period, the council does not need to sue you to enforce, and a live claim holds the period open. What is the 20-year rule for council tax debt in Scotland sets it out in full, and mygov.scot covers debts and decrees generally.
