I no that a common law partner use to have rights when living with their partner. My partner bought a house a couple of years ago in his name only, we both moved into it on receipt of keys. I have paid for bills and decorations. Will I be entitled to any of profits from sale after seperating.
Well, there is no such thing as common law in the UK
You paid for bills and decor, who paid the mortgage? Swings and roundabouts as far as 'paying bills' is concerned, it would be the same as if you paid rent
Unless your name is on the mortgage then no, you wont see a penny of the profits, sorry
The above answer is not strictly correct as improvements to the property etc can gain you an interest in the property. However I think most solicitors would point out that, as you were together when the property was purchased, and as you were not invited to be a party to the purchase and did not have your name added to the deeds or mortgage, there was never any intention for you to be a joint owner of the property, so I think you'd find it hard to claim otherwise in this case.
plus you would have had to pay bills no matter where you were living. You say you spent money on "decorations" what do you mean by that? Furniture and stuff? if so, take it with you. If you mean paint and tiles then surely those wouldnt give you beneficial interest in a house?
Also, it will depend on the other party selling. If it's their house, and they paid all the mortgage what makes you think they will sell it now you've split?
