You'd be better off talking to an atty. about this one. Once the judge removes the conditional order, he has every right to enter the home, since he does own it...and it would not be considered forcing his way in. If he does come back, I guess it would be possible that he could change the locks on you.......but like I said, you should contact an atty. to find out your rights.
JMO, but if it were me, I'd be getting to the bottom of the reason for the mutual fight (you did say 'we') to begin with.......that's a much bigger issue than changing the locks on the house. Remember that law enforcement is taught on the false belief that ALL males are at fault in domestic disputes, hence the reason why most of them are arrested, no questions asked. This also includes any situation where the male is the only one sporting the physical evidence (bruises, scratches, etc.). And to find the stats on that, go to glennsacks.com.
And before anyone decides to lambaste me for being insensitive to domestic violence victims, I've suffered it firsthand myself, having my neck almost broke by DS's father (which is why I left him) and physically assaulted by DH within the first few years of our marriage. At least DH and I were able to work things out.....
