Considering Divorce: what are my legal options?

I just got my BRP and returned to the UK, and well not to get into too many sordid details but I found evidence of cheating and I want to go back home asap.

What and where should I go? What are my legal options? Any help or resources would be greatly appreciated.

Oh no AM!

Do you have kids?  If you do, things get really tough, as you can only return to the US with his consent (which I would recommend doing through an attorney here before traveling).

Divorce is MUCH easier in the US, as there has to be a two year wait in the UK after separation.  So if you return to the US, I'd recommend filing there.

Big hugs.  Thinking of you.

So sorry to hear this AmericanMom.

I do have kids! Great summer vacation they're having!

Do I need to go to an attorney or can he just write me a letter stating I have permission? He said he won't stop me taking them.

If I were to stay in the U.K., would filing for a divorce revoke my BRP?

Fantastic!  Get him to sign away as soon as possible!  I'd do that legally here with a solicitor.  That way he can't change his tune after you get home.

If you stay in the UK and the marriage has truly broken down with no chance of reconciliation, you would need to notify UKVI.  You would then have to apply for Leave to Remain based on your children living in the UK, which would be a ten year path to ILR.

Keep us posted.  We are here for you.

Sorry to hear this AM

Not a two year wait for adultery or unreasonable behaviour, according to the internet. Lots like this-

Oh jeez AmericanMom, I am so sorry.

i am so sorry AmericanMom , we are all here for you. Please stay strong, let us know if we can help somehow. xxxx thinking of you

I'm so sorry American mom. That's a horrible thing to have happen after the long wait! Be strong, everyone here is behind you!

Heartbreaking news to find out. Hope you come out stronger from this. Good riddance to bad rubbish. Take care of yourself and the kids. Stay strong.

Hey American Mom,  I'm really sorry to hear that and I'm sure you are really upset.  I didn't see too many suggestions that you see a solicitor (other than good old KFDancer) , so I would suggest you do that right away. 
I'd also suggest that you talk to a professional who can help you make some decisions. Perhaps you could call Relate or another counselor for a start, or maybe your religious advisor if you have one. 

Good luck
