Illegal practice?

[Breadgunner]

My wife needed a legal letter to use to solve a legal issue between herself and her brother in-law.

Her brother in-law's lawyer said he'd write it for her to save her time and effort in a show of "good will"

She received it from him, signed it and sent it back.

It turns out he had cleverly written it in a way that made my wife appear guilty/responsible.
He's now trying to use it as evidence against her.
We have proof he wrote it.

Surely what this lawyer has done is illegal in any court?

Did she think the lawyer was acting for her? If so, what made her think that?

[Breadgunner]

She was struggling to write her letter properly and was worried. Her brother in-law said he'd ask his lawyer to help. He contacted her all friendly over the phone and said as an act of good will he'd type it up for her and forward it to her brother in-law who would give it her.

They tricked her into thinking it was just a minor issue that would run quicker if she let the lawyer write it.
She didn't have representation as it all happened and very fast.

[atticus]

did she read it before signing?

[Breadgunner]

Not really.
the lawyer made it sound like he needed in back in a hurry because he was doing it as a favor and her brother in-law was telling her to be quick.
