The Hidden Cost of New Law Proposals for Unmarried Couples

Thousands of unmarried couples across Newcastle and the North East could face new financial liabilities when relationships end under government proposals to reform cohabitation law in England and Wales.

The plans have been presented as a way to protect financially vulnerable partners. However, they could also produce expensive and unexpected consequences for people who deliberately chose not to marry or combine their assets.

Despite being widely described as a new unmarried couples finance law, the reforms are not yet law. A government consultation closed on 14 August 2026, and ministers must now consider the responses, finalise the policy and introduce legislation.

No commencement date has been announced. The government says implementation will take place when parliamentary time allows, meaning couples should not assume the changes are already in force.

What the proposed cohabitation law would do.

Under the proposed framework, unmarried couples would generally qualify after living together for three years. Couples living together with a shared child, or a child treated as part of the family, could qualify without waiting three years.

The framework would apply automatically. Couples could opt out, but only by mutual agreement and with safeguards that could include financial disclosure, a formal deed and independent legal advice for each partner.

Following separation, courts could be given powers to order lump-sum payments, property transfers and pension sharing. Maintenance could also be awarded in exceptional circumstances, such as serious ill health or disability.

These would not be automatic 50-50 settlements. Unlike divorce law, the proposed system would be based primarily on financial need rather than equal sharing. Nevertheless, someone who legally owns a home, savings or pension could face a claim from a former partner.

Why ministers want the law changed.

The government argues that existing cohabitation law has failed to keep pace with modern relationships. The UK now has more than 3.5 million cohabiting couples, more than twice the number recorded around 30 years ago.

At present, separating partners must often rely on complex property and trust law. A partner who stopped working to raise children may have little protection if the family home is registered solely in the other person’s name.

Another concern is the persistent “common-law marriage” myth. The government consultation reports that nearly half of the public incorrectly believe living together creates the same legal rights as marriage.

Ministers also want better protection for survivors of domestic and economic abuse. However, creating those protections could bring more couples into the court system and place new responsibilities on partners who never formally agreed to them. Read the government’s cohabitation proposals.

How North East couples could lose money.

Property is likely to be the biggest concern. The average Newcastle home was worth approximately £209,000 in June 2026, according to the Office for National Statistics. A property adjustment or lump-sum order involving even 10 per cent of that illustrative value would represent £20,900.

That is not an estimate of what a court would award. Every decision would depend on circumstances, ownership, resources and financial need. It demonstrates, however, how quickly a claim involving an ordinary Newcastle property could reach five figures.

The proposals could also affect retirement planning. Pension sharing would allow part of one partner’s pension to be transferred to the other. Someone with a £100,000 pension pot would see £20,000 moved if an illustrative 20 per cent order were made, although no standard percentage is proposed.

Couples who want to opt out could encounter immediate professional costs. Because the suggested safeguards require separate legal advice, both partners may need their own solicitor. Fees will vary substantially, but even several hours of advice, document preparation and financial disclosure could produce a combined bill running into four figures.

Disputed separations could be considerably more expensive. Solicitors, valuations, barristers and court proceedings can consume money that might otherwise fund two new households. The government itself acknowledges that greater litigation could increase legal costs and reduce the assets available for division.

Housing costs could deepen the impact.

A separation already means turning one household into two. That is particularly difficult in Newcastle, where average private rent reached £1,207 a month in July 2026, an annual increase of 9.8 per cent.

If both former partners rented homes at that average, their combined housing cost would be about £2,414 a month, before deposits, moving expenses and legal fees. Across the wider North East, average rent was lower at £783, but it had still risen 6.3 per cent over the year. See the latest ONS Newcastle housing figures.

The inheritance proposals would give qualifying partners potential automatic rights when someone dies without a will. That could protect a surviving partner, but it may also reduce what children or other relatives receive. Importantly, the consultation does not propose giving unmarried couples the inheritance-tax exemptions enjoyed by spouses and civil partners.

What couples should do now.

North East couples should review how their home is owned, check pension nominations and consider making or updating wills. Keeping evidence of deposits, mortgage payments and major renovations may also prevent later disagreement.

No one needs to opt out now because the framework is not yet law. Couples should follow the legislation rather than making costly decisions based on headlines. If the proposals become law, taking early advice could be cheaper than resolving an argument after separation.
