Diligence is simply the Scots word for the legal steps a creditor takes to get money out of you. What makes a diligence summary is where the authority came from.

Here is what summary diligence actually is, why it is a different thing from a summary warrant, and the prohibition that keeps it away from ordinary consumer credit. What a summary warrant is covers the council tax route.

It is diligence done on a private document that has been registered for execution in the Books of Council and Session or in sheriff court books. No sheriff grants anything, because the warrant is written into the extract by the registrar.

Where the warrant comes from

Section 1 of the Writs Execution (Scotland) Act 1877 requires the keeper of the register to insert a warrant for execution into the extract of any writ, deed or document that contains a clause of registration for preservation and execution.

The Act received Royal Assent on 10 August 1877 and came into force on 1 October 1877. Section 2 does the same job for sheriff court books.

What that warrant then allows

Section 3 of the 1877 Act, as substituted by the Debtors (Scotland) Act 1987, sets out what the inserted warrant authorises. It is a long list and it reaches wages.

Limb (c) is worth noting on its own, because it is the only route into a maintenance obligation in a registered document. What a current maintenance arrestment is explains that diligence.

Completely. A summary warrant is granted by a sheriff on a council’s certificate, and summary diligence needs no sheriff, no application and no grant by anybody.

Three routes, three different pieces of paper

Parliament put them in two different definitions

Section 10(5) of the Debt Arrangement and Attachment (Scotland) Act 2002 defines “decree” and “document of debt” separately. A summary warrant sits inside the definition of “decree”, at limb (c).

A document registered for execution in the Books of Council and Session or the sheriff court books sits inside the other definition, at limb (a) of “document of debt”. An article that runs the two together is contradicting the statute book.

Section 10(2) then ties both to the same rule: attachment is exigible only in execution of a decree or document of debt. The difference between a summary warrant and a decree deals with the other pair.

Why the confusion is so persistent

Both phrases start with the word summary, and council letters use “diligence” without explaining it. Whether you get taken to court for a summary warrant covers what a council actually does.

At the moment you signed the document, usually years before any default. The clause of registration for preservation and execution is the consent, and without it the Keeper inserts no warrant.

The 1995 Act confirms it by contrast

Section 6(4) of the Requirements of Writing (Scotland) Act 1995 provides that a traditional document may be registered for preservation without a clause of consent to registration. Registration for execution is the one that needs the clause.

Section 6(1) adds a second condition. Registration for execution is not competent unless the document is self-proving, which in practice means witnessed or otherwise attested.

The one consumer document verified to carry the clause

Schedule 2 to the Conveyancing and Feudal Reform (Scotland) Act 1970 gives two statutory forms of standard security. Form A, used where the personal obligation is in the deed, ends with the words “And I consent to registration for execution”.

Form B, used where the personal obligation sits in a separate instrument, has no such clause. So the consent is printed in the statutory form of one kind of Scottish mortgage deed and not the other.

What is not established is what lenders actually do with that consent. No source addresses how often, or whether, summary diligence is used on the personal obligation in a standard security.

What we do not claim

Separation agreements, guarantees, cautionary obligations and commercial leases are all commonly said to be registered for execution. No primary source was found for any of them and none is asserted here.

No. Section 93A of the Consumer Credit Act 1974 provides that summary diligence is not competent in Scotland to enforce payment of a debt due under a regulated agreement, or under any security related to one.

What that rules out

A regulated agreement under the 1974 Act covers most ordinary consumer borrowing. Credit cards, personal loans, store cards, hire purchase and catalogue credit sit inside it.

A creditor on any of those has to raise a court action and obtain a decree. It cannot short-cut to a charge for payment on the strength of the credit agreement.

When the prohibition came in

Section 93A of the Consumer Credit Act 1974 was inserted by the Debtors (Scotland) Act 1987 and came into force on 30 November 1988, along with the rest of that Act’s diligence regime.

This is the single most useful thing to know about the term. Which creditors can apply for a wage arrestment in Scotland sets out who has to sue you first.

Yes, and twice over. The 1877 Act warrant makes the arrestment conditional on a charge running out unpaid, and section 90(1) of the 1987 Act makes a charge a precondition of every earnings arrestment.

The protections attach to the diligence, not to the route

This is the most reassuring true thing about summary diligence. Section 47 of the 1987 Act is not qualified by the type of warrant behind it, so the safeguards are identical.

So the first document you would receive is the same document a council tax debtor receives. What a charge for payment is explains it, and the 14 days is the window to act in.

Goods carry their own precondition

Section 10(3) of the 2002 Act makes an attachment competent only where a charge has been served and has expired, and where a debt advice and information package was given no earlier than 12 weeks before any step to execute it.

The same things you could do against a decree. A time to pay order is competent, and so are the statutory debt solutions.

A time to pay order

Section 15(3)(b) of the 1987 Act lists an extract of a document registered for execution among the documents a time to pay order can be made against, so what a time to pay order is applies here in the same way.

Section 5(1) requires a charge to have been served, an arrestment to have been executed, or an action of adjudication to have been commenced. The debt outstanding must be £25,000 or less excluding interest, a limit in force since 10 July 2000.

The statutory solutions

An approved Debt Payment Programme under the Debt Arrangement Scheme stops an existing earnings arrestment, freezes interest, fees and charges and blocks new diligence. What the Debt Arrangement Scheme is explains it.

Section 50 of the 1987 Act also lets the sheriff declare an earnings arrestment invalid or spent, and settle a dispute about how it is being operated. Whether you can get a wage arrestment without going to court covers the wider question.

Because Parliament never has. The phrase appears in the statute book from at least 1877 onwards, and not one of the Acts that uses it contains a definition.

The clearest statutory acknowledgment

Section 98 of the Bills of Exchange Act 1882 is headed “Saving of summary diligence in Scotland”. It provides that nothing in that Act extends, restricts, alters or affects the law and practice in Scotland in regard to summary diligence.

Parliament legislated around the institution rather than describing it. That is why the term survives in letters without anyone explaining it.

How common is it?

Honestly, we do not know, and no official source establishes it. What is certain is the statutory prohibition on regulated agreements, which keeps it out of the debts most people owe, and guidance on debt and diligence sits on mygov.scot.

If a letter mentions diligence and you are not sure which kind, ask the creditor in writing what its authority is. Our council tax debt advice page covers the council tax version.
