Ive just found your post, otherwise I would have replied sooner.
I know from my own experience that splitting up with a long term partner is traumatic and emotional,and is a legal minefield, as the rights of co-habitees are almost non-existent in the UK.
Without any further details, it is difficult to answer your question fully. Prehaps you could let us know who paid the mortgage, whether you are in Scotland, England or Wales, etc.
I have given some basic information below (applies to England):-
As far as the house is concerned - On the face of it, you own the home in the shares that were specified when you bought the property. If you did not specify unequal shares, the law will treat you as owning it 50:50.
If a 50:50 split is not fair because of what you have both contributed, you can either negotiate a deal or take the issue to court. You would usually have to show that you had an agreement, whether written or simply understood, that you did not have equal shares and that you had
contributed unequally along the lines of this agreement. To get the jointly-owned house into your sole name,you wouldn need to "buy out" your partner. If there are children a court can order a transfer of the tenancy to a parent on behalf of the children under the Children Act 1989. This would typically happen to keep the children housed.
In practice this does not mean that you get a larger share of the home, but you may get the right to remain in it while it is the home for the children - until they reach 18 or leave full time education.
You can only sell the home if both owners agree to it. This often causes problems if one of you wants to stay in the house and can’t offer a fair price to buy the other’s
share. You can take the issue to court, but this is time consuming, costly, and stressful. Although the house is in the sole name of your former partner, now that you have registered your interest in it with the LR, it will make it far more difficult for him to simply sell the house without your knowledge or consent.
As for a finacial settlement - when couples that were living together break up neither partner is entitled to any maintenance from the other, and the court can’t order a transfer of savings or property that were owned by one of you (if it was always treated that way and the other one did not contribute towards it). However, if you both thought that such a transfer would be fair, you could make a voluntary agreement.
When you come to any sort of agreement between yourselves it is useful to write it down, including specifics like the amount and dates of any agreed payments, in case there is any dispute later on. If you have agreed to transfer property from one person to another you should consult a solicitor.
If you are unable to come to an agreement about financial issues you could take the matter to court, but this is likely to be a very drawn out and expensive business. You should only consider this as a last resort. You may want to consider using a mediation
service to help you arrive at a fair settlement
I hope this helps, and Im sorry its not going to be straightfoward for you - the rights of co-habitees needs a good shake up in the UK!
Get yourself down the CAB as soon as is possible, if you havent already done so.
If you feel like a moan, orjust wantsome company, pop into the chatroom - you will be made very welcome.
Take care, and keep posting
