Guarantors and joint borrowing carry the whole debt

The theory of guarantors and joint debt is well covered elsewhere. This is about the version you meet in practice.

Joint means all of it, not half

Joint and several liability means the lender may pursue either borrower for the entire outstanding balance. An informal agreement between the borrowers to split it has no effect on the lender.

This surprises people repeatedly, particularly after a relationship or a business partnership ends. In many countries an order dividing debts between separating partners binds the two of them and not the lender, which can still pursue whichever name it prefers.

Guarantees are broader than expected

A guarantor typically agrees to pay if the borrower does not, and the lender may pursue them without exhausting other options first. Some guarantees extend to future variations of the loan, which means the debt you guaranteed may not be the debt you end up owing. Reading the scope, including any all-monies wording, is essential before signing.

Put simply, where the borrower is a company, a personal guarantee generally survives the company failing, which is the entire reason lenders ask directors for one.

It affects your own borrowing

A guarantee or joint debt appears in your commitments and reduces what you can borrow. People discover this when applying for a mortgage years later and finding capacity mysteriously reduced.

It also links your file to the other party through financial association. The link runs both ways, so adverse data recorded against them can surface in assessments of you even while the guaranteed debt itself is being paid on time.

Getting out is hard

A guarantee generally cannot be withdrawn unilaterally while the debt exists. Removing a name from a joint mortgage requires the lender to agree the remaining borrower can afford it alone, which is a fresh assessment.

For most people, neither is a formality, and both are far easier to avoid than to unwind. If the lender refuses to release a name, the routes left are refinancing the whole debt elsewhere in one name or selling the asset, and both depend on the market rather than on either party agreeing.

If you are asked

The honest question is whether you could pay the whole balance without hardship, because that is the commitment. Where the answer is no, declining is the correct answer, and offering a smaller gift instead is often kinder to everyone. Where the answer is yes, get independent legal advice and understand the exact scope before signing.

For most people, independent means an adviser other than the one acting for the borrower, and some lenders require evidence of it precisely so the guarantee cannot later be challenged as uninformed.

Adjust the size of it until it is something you would actually do tired.

What happens if the borrower stops paying

The lender is often not obliged to chase the borrower first, and many agreements let it demand the whole balance from a guarantor on default rather than instalment by instalment. Missed payments on a joint account are recorded against both files, so the party still paying can carry adverse data caused entirely by the other.

Paying to protect your own file is a legitimate choice and does not give up any claim you may have against the other party, though recovering the money is a separate and usually civil matter. Where the sum is beyond what you can pay, free debt advice covers guarantors as well as borrowers, and the guarantee is worth disclosing to the adviser as your own debt rather than as somebody else's.

The takeaway

Only guarantee what you could pay in full tomorrow, because that is what you are agreeing to.

Small and repeatable beats ambitious and abandoned, almost every time.
