Definitley, if you don't trust him, make sure to only have people around your son that are trustworthy. e.g. no dodgy mate coming over. How old's your son?

Many of my friends have tricky custody arrangements and those that did it alone regret not hiring someone to advocate on their behalf. Attorneys are spend but a good one is worth its weight in gold.
Your child is worth it...

Hi there.

Goodluck with it all.

A good freind of mine recently lost custody of her two children at the second court hearing after being granted with custody 12months ago.

In her first agreement, there was such things as,

if he lives near, or close with family he can only have the child stay there with the grandparents while he has sharetime with them.

no smoking in the house around children.
certain days and times that dont affect the childrens normal routine.
if he has particular friends and stuff that you dont want your child around.

if you and him can come to some sort or agreement it would be heaps easier, because the courts are sometimes wrong and i wouldnt wish on any mother to lose her babies just because of what people say in court.
goodluck xx

No, No, No!
You may think your doing the right thing, but its the child that suffers!

I saw what custody hearings did to my cousin and it broke his heart not two see his two gorgeous children. The kids missed him and it hurt them as their very close to their dad.
I'm also seeing my other cousin (first cousin's younger brother), go through a custody battle and its doing more damage to his relationship with his ex and its doing damage to the kids. Its as if their a prize to be won and their own.

They're children.
They may not be old enough to have a say, but you never want to them go through that. They deserve both parents.

How would you feel if you were in your son's shoes. Would you want to be kept away from you father?
I think not.

People change when they have children, I never thought my latter cousin would be a good father (very troubled teen), but he's one of the best dad's I've ever seen.

Don't disavantage your child. You will regret it in the future.
