You cannot "prove" that the child would prosper more under your custody to a judge because there is no proof. If you seek to take custody away from the custodial parent you must provide evidence to the court that the custodial parent is unfit. Fortunately, income is not a decision maker for custody especially since most men have higher incomes than most women. Having more resources does not mean you would be a better parent or that your child would necessarily "prosper" under your sole custody. To a judge it could indicate that you could provide more support for the child and increase his standard of living.
Financial resources do not make a person a good parent. The primary characteristic of a good parent is being able and willing to place the child's needs above your own. You must be willing to spend quality time with the child and listen when she has something to say. You must be able to detect the child's needs when they don't or can't express them. You need to monitor what's going on in school and attend school meetings. You must monitor health and accompany the child to doctor/dentist visits. You must stay home or arrange for special care when the child is sick or on vacation from school. You must plan enriching activities and help with homework. Most of the important aspects of parenting do not include having more money than the other parent.

By filing for custody modification in the court with jurisdiction, then prove to the court why it would be in the best interests of your child to award joint custody.
The mother. The father have to prove paternity in court and petition for custody, visitation and can then also pay child support.
Yes if she could prove that the child is better off in her primary care. If the child is thriving and safe with you, it would be hard for her to prove. But custody can change at anytime so she has the right to file.
Yes! You need to either have custody or legal guardianship to receive child support, AND have the legal documentatio to prove it.
It would be very unlikely for a judge to award custody to a parent that isn't around. If the father could prove that the child would be better off with him, then maybe, but otherwise I don't think you have anything to worry about.
Sure, get a good lawyer to prove this point. If he only wants custody of your child when he's served with child support papers, this would be a red flag for a judge. Tell the court how long it's been since he's had anything to do with the child. A judge can see right through the smoke screen. No, as no attorney would tell a father this. Who would be supporting the child if he got custody? Only 15% of mothers are order to pay, of which 5% ever pay. That 1 out of 1000 custodial fathers getting child support. Further, even with sole custody, he can still be ordered to pay. At the current stage in fathers rights, this idea is an Urban Myth, though it may change now that more women are working than men and stay at home dads will have a greater chance of getting custody and child support as a growing number will have to go on Welfare.
To get soul custody of your children you must prove the other parent is unfit. If they have any addictions, proving they are unfit will not be hard.
Certainly, if they can prove to the court it would be in the best interests of the child to grant such custody.
You have to prove your case and convince the court.
