The instinct is that it must have lapsed. It has not, but three other things in the process do have clocks on them, and they get confused with this one constantly.

Here is why the warrant has no shelf life, which clocks actually run, and what a council still has to do before it can act on an old one. What a summary warrant is covers the document.

Because the statute that creates it does not give it one. Schedule 8 runs from paragraph 1 to paragraph 6 and none of them sets a period within which the warrant must be used.

What Schedule 8 does and does not contain

Paragraph 2(2) of Schedule 8 to the Local Government Finance Act 1992 tells the sheriff to grant the warrant and tells you what it authorises. It says nothing at all about how long that authority lasts.

The same is true of the sibling provisions. Section 247 of the Local Government (Scotland) Act 1947 for non-domestic rates, and Schedule 4 to the Water Industry (Scotland) Act 2002 for water and sewerage, are drafted in the same terms and set no period either.

The only thing that makes a warrant cease to have effect

Paragraph 2(4) is the single provision in Schedule 8 that ends a live warrant. If the council raises an ordinary court action for the same sum, any existing warrant for that sum stops having effect.

That is the council’s choice rather than something age brings about, and paragraph 2(5) then bars the action once a diligence has been executed. The difference between a summary warrant and a decree sets out the two routes.

What not to conclude from that

A warrant having no expiry is not the same as the debt having no expiry. The two questions are separate and the answers are different.

It is also why nobody can tell you that a summary warrant lasts for a set number of years. There is no figure to give, and a page offering one has invented it.

It belongs to the charge for payment, not to the warrant. Under section 90(5) of the Debtors (Scotland) Act 1987 it is not competent to execute diligence by virtue of a charge more than two years after it was served.

How the two-year rule actually works

Section 90(6) of the Debtors (Scotland) Act 1987 lets a creditor reconstitute the right to execute diligence by serving a further charge. So the two years ends the usefulness of that piece of paper, not the recovery.

Section 90(7) adds a small protection. No expenses incurred in serving a further charge within two years of the first are chargeable against you.

Section 90(3) sets the period for payment at 14 days if you are in the United Kingdom and 28 days if you are not. What a charge for payment is explains the document itself.

When the two years does and does not bite

Where a charge is required, that two-year life is the real practical limit on a wage arrestment, because a warrant more than two years past its charge cannot be used until a fresh charge is served.

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 web page should tell you the answer either way. Ask a money adviser or the sheriff clerk what applies on your own account before relying on it.

It does bite on goods. Section 10(3) of the Debt Arrangement and Attachment (Scotland) Act 2002 makes an attachment competent only where a charge has been served and expired, so a stale charge has to be replaced first.

That is the one place where the age of the paperwork really does stop a council in its tracks. What an attachment order is and how it works covers that diligence.

The clocks side by side

Council tax sits on the twenty-year long negative prescription in section 7 of the Prescription and Limitation (Scotland) Act 1973, because Schedule 1 paragraph 2(fd) excludes it from the five-year rule that clears most consumer debt.

What changed on 28 February 2025

Enforcement does not send the clock back to the start. Since 28 February 2025 a relevant claim, which includes executing diligence, extends the twenty-year period until that claim is finally disposed of.

Before that date it restarted the period, and a great deal of published advice has not caught up.

Payment does not touch the twenty years

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.

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.

Who has to prove it

Section 13A, 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.

That is a change in who produces the paperwork rather than a rule you can count yourself. What the 20-year rule for council tax debt in Scotland is goes through it properly, and how far back a council can chase council tax arrears covers the practical side.

Yes. Nothing makes the warrant go stale, but the steps taken under it have their own freshness requirements and those are where an old file can trip up.

What still has to be in place

The twelve weeks is the one to know

Section 47(3) of the 1987 Act says an earnings arrestment does not come into effect unless the creditor gave you a debt advice and information package no earlier than 12 weeks before the schedule was served.

So the paperwork that matters on an old account is recent by definition, whatever the date on the warrant. What documents you should receive before a wage arrestment lists them.

A warrant does not have to be re-applied for

There is no requirement to renew a summary warrant and no use-it-or-lose-it rule. A council can hold one and instruct sheriff officers on it years later.

What often looks like a new warrant is a new financial year. Each year is billed separately and each unpaid year can carry its own warrant and its own 10%.

No. Age is not a ground, because Schedule 8 provides no appeal and gives the warrant no lifespan for it to have exceeded.

What can be argued instead

The arguments that work go at the bill behind the warrant or at the diligence carried out under it. Whether you can appeal a summary warrant sets out the five routes.

Paragraph 3 of Schedule 8 also removes the two instinctive arguments. A missed council deadline and a mistake in a notice are both ruled out expressly.

Where prescription might come into it

None of that makes an old council tax balance safe to ignore. Twenty years is a long period, the council does not need to sue you to enforce, and a live claim holds the period open.

Ask for a breakdown by financial year and take it to a money adviser rather than counting years yourself.

Get the dates in writing before you agree to anything. You want the years the arrears relate to, the dates of any warrants, and the dates of any enforcement action.

What to ask the council for

• A statement showing the balance owed for each financial year separately.
• The date any summary warrant was granted, for each year.
• A list of the enforcement action taken on the account, and when.
• Confirmation of the 10% statutory addition and any sheriff officer fees on each year.

Check liability before you check the calendar

If you were not the liable person for a particular address or period, that is a stronger point than age. Raise it in writing, and whether a council can add charges to your council tax arrears covers what else may be sitting on the balance.

Then deal with what is left

There is no statutory maximum period for spreading council tax arrears, so a longer plan is a competent thing to ask for. Our council tax debt advice page sets out how we help.
