Do both people have to sign

[Timothy Mckenney]

I purchased a Moduler and I met a girl who wanted to sell her condo and her mother’s name was on the condo also and her mother would not sign off the condo until she seen her daughter’s name on my title and we are not married but now I want to remove her from the title and have it back in just my name again so do we both have to sign the title to remove her
