Tina Knowles, mother of singer Beyonce Knowles, has filed for divorce from her husband Mathew Knowles. Tina Knowles apparently filed last month in Harris County, Texas. The couple has been married for almost 31 years.

The divorce paperwork indicates that the couple separated last January. Back in October, Mathew Knowles was served with a paternity lawsuit filed in California by another woman. At the time, this woman was six months pregnant – so it now appears that the pregnancy happened after Mathew and Tina Knowles split.

The Knowles have two grown children: Beyonce and her younger sister, Solange (who is also a singer). Mathew Knowles was the manager of Beyonce’s group Destiny’s Child and is currently managing her solo career. Tina Knowles was Destiny Child’s costume designer and now designs for Beyonce’s fashion label, House of Dereon.

Because of their involvement with Beyonce’s (and to a lesser degree, Solange’s) career over the years, the Knowles are likely very wealthy. They each appear to have active careers (however tied to Beyonce’s that they might be).

As Texas is a community property state, the Knowles will very likely split their marital assets and debts equally. Unless one or the other entered the marriage with substantial property or inherited property during the marriage, all of their wealth is likely to be considered community property and available for equal distribution.
