Estate Planning, Wills and Trusts, Probate and

Estate Administration

Customized services from experienced attorneys

in the convenience of your own home




Estate Planning

About two-thirds of Americans don't have a written will. A will is important for everyone, young and old, single or married, with children or without. It can make a very difficult time just a little bit easier for your family should the unexpected happen. Most people realize the importance of having a will or living trust, but there never seems to be a good time to locate a trusted attorney, schedule an appointment and travel to the attorney's office.  We can help you update an existing will or trust or create a new one, conveniently and comfortably in your own home or office. 

Probate and Estate Administration

There is enough to deal with after a loved one passes.  The next steps are often unclear.  Let us guide you through the Probate process.  Whether you are dealing with a Will needing to be probated, a trust administration outside of the traditional court process or a case where the decedent did not have a Will, we will discuss your options, determine the least expensive method available and assist you through the process. We are often hired to handle the legal work necessary to administer an estate so that our clients have the time and energy to focus on what matters during a difficult time, their family and loved ones. 


As the executor under a will or the trustee of a trust, there are many legal and fiduciary obligations that you are required to fulfill.  You cannot do it on your own. Our job, as the attorney for the estate representative or trustee, is to keep you in compliance with the law and help you settle the estate in a timely and straightforward manner.

Corporate and Partnership


There are many things to review when attempting to establish a new business entity. The selection and formation of a new business should preferably be done with the assistance and legal advice from an attorney.  With adequate legal counsel regarding your goals for your business, the correct type of business structure can be determined. Whether you are forming a partnership, are a sole proprietor, or wish to establish a corporation, we can assist you with determining the appropriate legal structure.


Depending on your type of business, there can be a variety of business entities that will be right for you. A small business owner working out of his/her home without employees may simply need to be structured as a sole proprietorship.  A somewhat larger business with employees and an office may need to protect assets and be taxed appropriately as a corporation, either an S Corp or C Corp.  In some situations, a Limited Liability Company (LLC) is the best choice.



We are South Texas attorneys with over 65 years of combined experience.  We focus exclusively on Estate Planning, Probate and Business law.  Our goal is to provide expert legal advice and representation as we build long-term client relationships with you and your family, and we do so when and where it is convenient for you.  We are among just a few attorneys who make house calls.  We have found that our clients love being able to tend to important legal matters at their convenience and in the comfort and privacy of their own home.  Life is hectic.  It can be difficult to find time during your day to visit an attorney's office.  We can do most consultations over the phone, share information via email and when the time comes to sign legal documents, we can come to you.
