? about rights when never married

i am new to this. my question is my significant other (we were never legally married) left after living with eachother and 1 child after 13 years. the house is in both our names, i just do not have any idea what his responsibilities are towards the money for the house? i live in NJ. If anyone has any info it would be greatly appreciated.

If two or more owners cannot agree on what to do with a piece of property they may petition the court and the court will order a sale or refinancing etc. so that the one or more may get out of the property obligation and/or the other(s) may keep it etc.--it is often done-- (This is true in some cases even for equitable owners that have paid various amounts etc., but for various reasons, may not be on title.) You could threaten to take this action if need be. It may cause compromise which is of course what you need here now.
