If your listing agreement was written on Texas Association of Realtors Form (TAR 1101), and you have exclusively re-listed the home with another broker who is a member of TAR, then you don't need to worry. Just carefully read Section 5E. It explains everything. There are rules requiring the broker to give you a list of potential buyers that have seen the property, etc.
If you haven't relisted with another agent, then you should wait 30 days before doing anything to avoid paying commissions. Honestly, IMHO, if you haven't re-listed and can afford it, just wait it out if you are trying to do this yourself. You will avoid alot of trouble should the 1st agent decide to pursue procuring cause.
If you are planning to re-list - read that paragraph and if you feel comfortable, full speed ahead! Good Luck!
