People commonly prioritise the debt with the highest interest rate, which is not always the debt with the worst consequences.
Secured debt
Backed by an asset the lender can recover.
Which includes mortgages and vehicle finance.
Unsecured debt
No specific asset attached.
Which means enforcement requires court action.
Priority debts
Housing, utilities, taxes and court fines.
Which carry consequences beyond credit damage.
The ordering that matters
Consequence of non-payment first, interest rate second.
Which is the reverse of most popular advice.
Enforcement routes
Repossession for secured debt and court judgment for unsecured.
Which are very different timelines and consequences.
Secured enforcement is faster and more damaging in practical terms.
Priority in practice
Rent or mortgage, utilities, council or property taxes, then everything else.
Which is the ordering debt advisers use.
Charging orders
Unsecured debt converted into a charge against property by court order.
Which is possible in some jurisdictions and changes the nature of the debt.
Hire purchase and conditional sale
Agreements where the asset is not yet owned.
Which carry different protections from a loan used to buy an asset.
The practical rule
Ask what happens if you stop paying, and let the answer set the order.
Why the common advice misleads
Paying the highest interest rate first is correct when all debts have similar consequences.
Which is not the case when one of them is your rent and another is a credit card.
Losing accommodation is worse than paying more interest, and the ordering should reflect that.
What counts as a priority debt
Anything where non-payment can cost you your home, your liberty, an essential service or your employment.
Which is the practical definition advisers work from.
Vehicle finance
Repossession where the vehicle is needed for work.
Which makes it a priority in practical terms even where the law treats it otherwise.
Negotiating with secured lenders
Generally more willing to arrange than to enforce.
Which favours early contact.
A general note
Which debts count as priority differs by jurisdiction; free debt advice services will apply the correct local ordering.
Building the priority list
Write down every debt and next to each what happens if you stop paying it.
Which produces the correct ordering almost automatically.
People are frequently paying a credit card while falling behind on rent, because the card sends more letters.
Communication with creditors
Non-priority creditors will generally accept reduced payments while priorities are addressed.
Which is standard practice and requires asking.
Enforcement agents
Powers varying by debt type and by jurisdiction.
Which are more limited than is often assumed and are worth knowing.
Utilities and essential services
Payment plans and hardship schemes.
Which exist with most providers and are underused.
The summary
Sort debts by consequence rather than by interest rate, address the priorities first, and get free advice to confirm the ordering for your jurisdiction.
What creditors can actually do
Unsecured creditors must obtain a court judgment before most enforcement.
Which takes time and gives the debtor opportunities to respond.
Secured creditors have a defined route to the asset, which is faster and considerably harder to interrupt.
Responding to court papers
Deadlines that matter enormously.
Which is where people most commonly lose ground by doing nothing.
Even an admission with an offer to pay is better than no response at all.
Attachment of earnings
Deductions from wages under a court order.
Which is one enforcement route among several.
Getting the ordering right
A free adviser will produce a priority list in minutes based on your jurisdiction.
Where to get help that costs nothing
Most countries have free, regulated debt advice services funded by government, charity or by the creditor sector itself. They will review your whole position, explain every option available in your jurisdiction, and deal with creditors on your behalf if you ask them to.
They do not sell products, they do not charge, and they deal with situations far worse than yours every working day without judgement. The most common thing their advisers say is that people contact them years later than they should have.
Commercial firms offering the same services for a fee exist alongside them and are frequently advertised more heavily, which is the main reason many people never find the free option.
A general note
This article describes how these arrangements generally work and is not financial or legal advice. Rules, protections, terminology and available solutions differ substantially between countries and change over time, and anything with consequences for your home, your credit standing or your legal position warrants advice specific to your circumstances.
One thing worth remembering
Debt problems are experienced as personal failure and are usually the result of something ordinary: an income drop, an illness, a relationship ending, a bill that was larger than expected.
The people who resolve them are not more disciplined than everyone else. They are generally the ones who opened the letters, wrote down what was owed to whom, and asked someone for help earlier than felt comfortable.
None of those three steps costs anything, and all of them get harder the longer they are postponed.
