Not sure if anyone here can offer advice or if anyone just has suggestions. I am attempting to divorce my estranged wife under cover without setting off any alarms, so she doesn't have time to mount a defense. As of now I have told her we are separated and going to wait a year to see if we still want to stay married, she agreed, (basically because it means i'll keep paying everything while she does whatever she wants). So I am attempting to get all court documents and paperwork together to have her served before the end of the summer...here is my question:

We are both on the lease of her current townhome. We have two kids so I feel obligated to ensure there is a roof over her head for now, but the lease just expired, and we must sign a new one by the end of June. I am hesitant to sign it because of my plans. I don't want to still be liable for her stuff after it goes down. If i co-sign this lease with her can I be held legally responsible for the payment of that lease once we divorce if she doesn't pay it?

Further AITA for not worrying about her monthly payments to rent with my kids in that house? (I am a traveling contractor who cannot take the kids, custody wise)

Thanks for any help offered.
