by law are you consider married leaving with you partner after 4 years with a child?
It's called common law marriage and varies by state. I think my state is 7 years.
No b/c you don't have legal documentation
No. You actually have to get married to be legally considered married.
Actually I think it depends on the state you live in. I know in Missouri it's 9+ years, it's not a marriage but something similar, I just can't think of the title of it.
Depends on the state
No. You need to actually get married
