Family Law

Uncontested Family Law matters including Divorce, Legal Separation, Paternity, Domestic Partnerships, Child Custody, Spousal and Child Support, Prenuptial Agreements, and Postmarital Agreements.


Family Law matters including Divorce (Dissolution), Legal Separation, Paternity (Unmarried Parents).

Did you know most family matters are resolved out of court?  Even if the parties don't agree on everything, working with a skilled Mediator can be a very effective way to work through any differences and reach an agreement.  Mediation also saves the parties time, money, and reduces stress.  If minor children are involved, Mediation is highly recommended to protect the children from the issues and disputes of the parties.

Estate Planning

Wills, Trusts, Powers of Attorney, and Healthcare Directives.
