How to divide property in polygamous divorce

I am the first wife in a polygamous marriage, contemplating divorce due to irreconcilable differences. My husband and I have been married for over 15 years. He recently found success with real estate investments and began engaging with other women. My concerns stem from the fact that I took a loan from my Sacco to assist him in purchasing plots, where we jointly constructed rental houses in Kitengela and Mlolongo. Unfortunately, subsequent relationships have not only strained our marriage but also jeopardized our investments.

My husband married the other two women through customary ceremonies. Consequently, I have decided to seek a divorce. I have consulted with friends and colleagues for advice and have come to the conclusion that ending the marriage is the best course of action. I believe I have valid grounds for filing for divorce and am now seeking legal guidance on how to fairly divide our real estate investments, considering the complexities of a polygamous marriage.
