Real Estate / Poland property ownership question - becoming a half owner of the house without marriage? [3]

Hi everyone,

If somebody has any advice would be much appreciated, here is my situation.

I'm from UK originally currently living in Wroclaw with my gilfriend, who is from Wroclaw. Were having a baby soon and are living in a house together. The house is in her name only at the moment, but I am paying the mortgage costs.

My questin is if it's possible to become a half owner of the house, without being married? If anybody could recommend a relevant lawyer in Wroclaw also would be great.

Cheers.
