A 27-year-old woman who claims to have been married to Olympic marathon champion Samuel Wanjiru has sued to force the athlete's widow Teresiah Njeri and mother Hannah Wanjiru to file a succession case.

Judy Wambui who claims her 15-month-old child is Wanjiru's wants the two women to seek letters of administration over the athlete's estate failure to which she wants the High Court in Nakuru to allow her to administer the estate.

Wambui hopes that with the letters of administration, the family can institute a succession case that will see the athlete's estate sub-divided among his dependants and beneficiaries.

In an application before Judge Roselyne Wendoh yesterday morning, Wambui through her lawyer Kahiga Waitindi said prior to Wanjiru's death on May 15 last year, she was supported and maintained by the athlete and has been struggling to make ends meet since his death.

"I am a widow to the late Samuel Wanjiru who passed away under unclear circumstances. It has always been suspected that he was murdered although the matter is still under police investigations," Wambui said in the documents.

She claims that Wanjiru lived with her at her house in Nakuru town whenever he was in the country. On August 24 last year, Wambui gave birth to a baby boy who DNA tests later confirmed is Wanjiru's biological son.

Wambui now alleges that she is having a hard time raising her son. She had told Wendoh that she has unsuccessfully written to the two women hoping to convince them to start the process of petitioning the court for letters of administration in order for her to get a share of the estate that is meant for her son as one of his father's heirs.

"It is clear that they are settled in life as despite filing this case on March 22 this year, they have not replied. They may not be in a hurry to apply for letters of administration unless this court intervenes," Wambui said.

On Thursday, Hannah Wanjiru's lawyers told the court that they need two weeks to file a reply to Wambui's suit. Teresiah's lawyers on the other hand asked for a month.

Wendo gave the parties 21 days to file their reply and serve the other parties concerned following which the court will fix a hearing date.
