Contested Divorce

A Divorce legally dissolves a marriage and releases both parties from the responsibilities of their union. Ensure that you have a trusted attorney on your side to protect your legal rights, represent you in court, and negotiate your custody, visitation, division of property, etc.

Prenuptial Agreement

A Prenuptial Agreement is a written agreement between a couple made prior to marriage that governs asset possession, treatment of future earnings, property division, etc… in case you get divorced. From a legal standpoint, marriage is a legally binding contract made between two adults. As a proactive approach to protecting current assets, future earnings, business ventures, property divisions, parental rights, etc., a prenup is required. Your Prenuptial Agreement will ensure that your expectations are clearly defined, and that your assets and interests are protected. Contact our law office today to get started.

Uncontested Divorce

An Uncontested Divorce is one in which both spouses usually agree on all issues of custody, visitation, division of property, etc. An Uncontested Divorce legally dissolves a marriage and releases both parties from the responsibilities of their union. Ensure that you have a trusted attorney on your side to protect your legal rights.

Name Change

Our law office can help you legally change your maiden name back to what it was prior to marriage. Please contact us if you would like a Name Change for divorce reasons or any reason at all.

Estate Planning

A Will allows you to take a proactive approach to protecting your family, your assets, and your intended plans for all that you have worked hard to accomplish. Appoint an Executor to manage your estate and distribute your property exactly as you wish. Appoint guardianship of your children in the event of an untimely demise. Ease your family’s stress by clearly defining your wishes, and bypassing the lengthy probate process that will ensure if a Will is not established.
Power of Attorney
A Power of Attorney allows you to select someone (your Agent) to manage your affairs on your behalf, or “act in your place” if permanently or temporarily incapacitated. If you do not specify your preferred Power of Attorney, your affairs could be left in the wrong hands, and your intentions for your assets and finances skewed. A Power of Attorney does not extend to health and medical care.
Health Care Proxy

A Health Care Proxy allows you to choose someone (your Agent) to make general or specific health care decisions on your behalf if you are temporarily or permanently unable to do so. If you appoint no Health Care Proxy, decisions are likely to fall on your next of kin. Appoint a Health Care Proxy, and ensure that your health care wishes are respected.

Living Will

A Health Care Proxy appoints someone to specifically manage your medical care in the event you are unable to do so. While a Living Will does not appoint a specific proxy, it allows you to outline your healthcare wishes in the event that you are able to speak or act on your own behalf. Reach out to me today to ensure that your medical care is managed with the dignity and respect you deserve.

Revocable Living Trust

Revocable Living Trust can help you avoid probate and provide both privacy and continuity of asset management. Please contact our law office today if you would like us to set up a Revocable Living Trust for you.
