Exp has gone too far in his lies

[bongobaby]

exp has presented the judge with a totally false statement written in exp handwriting but signed by his father as a true statement of events and that he will be willing to attend court.
Whilst I sadly find it the norm for exp to churn out his lies, I am thinking why an earth would you get your elderly father to lie, sign a statement that is going to be presented before a judge. Surely a son would not want his own father to perjure himself.
He creeps me out at the actual lengths he goes to, to concoct these lies and drag other people into it.

Does his father know the truth, or does he just believe the lies?

I think that possibly his father has been made to lie by his son or that the father doesn't know that his son has written this statement and has falsely signed it in his name. Either way it's disgusting to put your own father in the position of lying before a judge. And not really the actions of a same person.

Some people will do anything for their children. Maybe his father sees this as supporting his son, maybe the father dictated it. Unfortunately you don't know what has gone on, you can only hope that the court resolves your issues.

It is not unusual for witness statements to be drafted by a third party (usually a lawyer) and signed by the witness - so I would not focus on the handwriting, as that is a non issue.

Of course, the witness can only attest to the veracity of facts they have personal knowledge of; so your FIL can only give evidence about things he knows. If the statement contains statements about facts he does not personally know about, that is hearsay evidence, and carries very little, or no, weight. If the statement contains lies, and he is exposed in court as having lied, then he may be guilty of perjury.

I have to give a lot of statements as part of my job. The police write them in front of me in my words and i sign them. I am not sure how much weight this unverified statement will have in court.
