We want to help you preserve your relationships and your assets.



Divorce is the process which legally dissolves a marriage. Related issues such as division of property, spousal support, and child custody can be resolved by negotiation, mediation, the collaborative process and/or trial.


Child Custody (SAPCR)

When parties are not married & there is no prior order, the term child custody is used to describe conservatorship, possession & support of a child.  The filing for this type of action is called Suit Affecting Parent-Child Relationship (SAPCR).



Modification occurs when there is reason to modify an existing order such as a divorce decree or other child custody order. The grounds for a change of conservatorship, possession & support of a child are complex and primarily based on the child’s best interest.



Enforcements in family law cases are filed when a party violates temporary orders, a decree of divorce, or other final order and usually involves unpaid child support or spousal maintenance, violations of possession orders, and failure to divide or deliver property.

Attorney-Client Confidentiality

The attorney-client relationship is one in which confidentiality and trust are cornerstones. In this process, you must be willing to accept (although it may be difficult at times) our guidance, advice, and mentorship. Helping you navigate the legal aspects of your case is critical, but so is making sure that once your case is completed your financial resources and relationships are preserved. We want the attorney-client relationship to be one of growth and opportunity for you and one that empowers you to confidently write the rest of your life story.
