I solely owned my house. My partner lived with me for 7 years. When needing new windows, I signed the contract and because my partner was a man, the company assumed he was my husband so asked him to sign too. I didn't think at the time. I'm scared he will get copied from the firm to try to help prove his claim through the courts. Can I insist the window company sends me back all paperwork relating to this work so he can't get copies? This is potentially so important so any legal thoughts would help significantly to protect my proceeds.
