While mediation is absolutely worth trying for most couples, not every couple belongs in mediation. For example, if there is domestic violence in your relationship, you should consider carefully before you agree to participate—but don't it out of hand. Some people who have experienced abuse in their marriages find it empowering to meet on the level playing field of a mediation session; others find there's too great a chance of replicating the dynamics of the marriage and choose to have a lawyer do their negotiating for them. Also, because the mediator can't order either of you to do anything, a person who wants to delay the proceedings or avoid paying support can abuse the process by agreeing to mediation and then stalling the process. If you need decisions about support or other issues made early in your divorce, you may need to go to court. This doesn't mean you won't be able to use mediation at a later point to resolve the rest of the issues in your divorce, though.

States regulate the manner in which marriages may be dissolved (i.e. divorce), just as they regulate the marriage process itself. These regulations often include residency requirements, waiting periods, acceptable grounds for divorce, and defenses to divorce filings. Like many family laws, the legal requirements for divorce have changed drastically over the course of history to reflect the times. For instance, a spouse who wanted a divorce had to first prove the other party's fault (such as adultery or desertion) before the advent of "no-fault" divorce.
When deciding which party to award a marital pet, a compelling argument is the pet’s attachment to the children. If there are minor children involved, who are very attached to the pet, the Court will likely award the pet to whichever parent has primary residence of the children. Another compelling argument is which party cares most for the pet. If you can prove that you were the one primarily responsible for feeding the pet, taking it to the vet, walking it, etcetera, then you will be much more likely to be awarded the pet.
Applying that rule, however, is far from straightforward. Courts must weigh a wide range of considerations. Generally speaking, children do best when they have ongoing contact with both parents. Yet that doesn't necessarily mean a 50-50 time-sharing arrangement. Instead, it depends on what works best for your family - and what will best serve the needs of the children.
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.
