I’ve heard of cases in which one spouse is so eager for custody of the children that they will relieve the other spouse of any duty to pay child support—which is not in their or the children’s best interests. Green says, “This is explicitly contrary to New York legislative policy—the kids shouldn’t be bargained for the money. The two things are determined separately by the court, so there’s no reason to take less than you’re entitled to under the formula.”
Another important tool for a parent whose child has been taken or hidden is the Federal Parent Locator Service (FPLS). An attorney must ask the court or county attorney to request FPLS assistance. The court or county attorney can apply to the FPLS for assistance in locating the missing parent. The FPLS is a computer search using the Social Security number of the missing parent to find home and work addresses for that parent. You must have the correct Social Security number in order to use the FPLS.
After the elapse of a period of time, nobody much cares if the reason you only had every other weekend was because the other parent truly wouldn’t “let” you have more time. Although that may very well be the case, and although you may have let your spouse control the situation in order to spare the children the trauma of parental conflict, in my experience the courts are more swayed by the pattern of contact rather than by these “excuses.” The wisdom of Solomon does not apply. 
Some spouses are under the impression that they must obtain a legal separation to get divorced. To the contrary, legal separation is an alternative to divorce, but the process is almost identical: you file legal paperwork, deal with all the same issues in a divorce, and ask a judge for an order of legal separation. If you plan to divorce, a legal separation is unnecessary and will only increase the total cost of the divorce.
If the parents can not agree on an appropriate custody arrangement, the court will examine what is in "the best interests of the child" by considering and evaluating the following factors: (1) the wishes of the child's parent or parents as to custody; (2) the reasonable preference of the child, if the court deems the child to be of sufficient age to express preference; (3) the child's primary caretaker; (4) the intimacy of the relationship between each parent and the child; (5) the interaction and interrelationship of the child with a parent or parents, siblings, and any other person who may significantly affect the child's best interests; (6) the child's adjustment to home, school, and community; (7) the length of time the child has lived in a stable, satisfactory environment and the desirability of maintaining continuity; (8) the permanence, as a family unit, of the existing or proposed custodial home; (9) the mental and physical health of all individuals involved; (10) the capacity and disposition of the parties to give the child love, affection, and guidance, and to continue educating and raising the child in the child's culture and religion or creed, if any; (11) the child's cultural background; (12) the effect on the child of the actions of an abuser; (13) except in cases in which a finding of domestic abuse, the disposition of each parent to encourage and permit frequent and continuing contact by the other parent with the child. (Minnesota Statutes - Chapters: 518.17)
With respect to financial issues, this same rule applies, as modified by the additional consideration of attorney’s fees. For example, it might be very likely that the court would award you $10,000 more in assets than your spouse is proposing, but if it will cost you $20,000 in attorney’s fees to litigate over it, it doesn’t make much sense from a purely practical, financial standpoint to do so.
Mediation is flexible and confidential. It gives you and your spouse a way to settle the conflict between you in a way that helps you to work together as parents. This is extremely important if you have children and must interact with your ex-spouse after you are divorced. Mediation brings about communication between the couple, which can then be used when they must discuss issues in pertaining to the children. Lack of communication may have been one of the main reasons for their divorce. Mediation has the ability to help the couple learn to communicate again, if only for the sake of the children, and make their post-divorce relationship better than their married one.
NOTE: There are many ways to divide real estate in a divorce. The court forms for marriage dissolution (divorce) only give you 1 option -- one spouse gets 100% of the house, cabin, or other real estate, and the other spouse gets a lien. But, you can change the court forms. An attorney can explain other options, advise you about the law, and draft terms to meet your situation. If your divorce involves real estate, you should get advice from a lawyer on your legal rights and options.
