Can someone of the opposite gender stay the night while there is a child there?

no its not iligal ignore the others all you did was ask a question

No, they aren't breaking any laws. Do you stay over at his place when the kid is there?

Oooo, past 10 p.m. That must mean she is a whore.

Wow, you are a prude. (and I"m fairly prudish myself, but that's ridiculous).

There is nothing illegal, even if he lives there full time when the child is there and they sleep together.

This is none of your business. It sounds like you want to trash the kid's relationship with the mother. Shame on you. You should NOT marry the man unless you can accept she is the mother and that gives her more rights than you will ever have.

Yes. The man can stay the night. No she isn't breaking any laws.

She isn't living in a convent ... she can have all the sex she wants with whoever she wants. Being a mom doesn't change that.

If they are in a relationship and share a child together as well as live together, they would likely be living common law wouldn't they? Which means he would certainly be there past 10 pm as that is his home. What a law breaker he is.

NO And it,s time You learned to mind Your own business.
