My husband ( hopefully soon to be ex) committed adultery.
Irrelevant to financial split, child access etc.
We have a shared mortgage together and two kids. He's taken all his stuff and isn't staying here anymore, he seems to think he still lives here, I say he doesn't. And hasn't for 3 weeks. Can he gain access to the house whenever he wants? Or is that then harassment?
In the absence of a court order:
1.Yes, he can gain access to the house as he is joint owner & he can even move back in if he wishes.
- No, the above would not constitute harassment as he has as much right to the house as you do at the moment.
Also, he can't make me sell the house can he until our youngest is 18
This is wrong, he absolutely can go to court to force the sale of the house & in the absence of any extenuating circumstances, there’s a very high probability that a court would order the sale as they tend to favour clean breaks now as opposed to mesher orders. Even if a mesher order were to be granted, there are certain situations that could trigger the sale of the house before the youngest turns 18. You would also be expected to cover all bills / mortgage on your own (unless he is a high earner).
but he would still be on the mortgage until I could buy him out
As above, it is very unlikely that a court would issue a mesher order & order him to stay on the mortgage, especially if he is not a high earner & doing so would hinder is ability to buy another property so he could house himself & the children.
would he still be able to have access then?
No, it can be written into the court order that he has no access should one be granted.
As stated above, in the absences of extenuating circumstances (disability etc) or him being a high earner, it is very unlikely that a mesher order be granted, especially as yours is considered a short marriage & you are both young, HOWEVER, please seek legal advice as people can only speak in generalities on this board. You need to speak to a solicitor who can advise you based on your specific circumstances.
