By Jel Santos  Actor Gabby Concepcion, Gabriel Arellano Concepcion in real life, is facing falsification of public documents case filed by his younger brother, Miguel Concepcion, for the alleged fraudulent sale of an 890-sqm lot owned by their mother in San Juan City. Gabby Concepcion (MANILA BULLETIN ENTERTAINMENT) Tyrone Cimafranca, lawyer of Miguel, said Mrs. Maria Lourdes Concepcion Arellano could not have sold the piece of land located at 3736 P. Guevarra St., in Barangay Addition Hills for P4.45 million for she was out of the country when it was notarized. "Their mother was in the United States and could not have signed the documents nor appeared infront of the notary public as stated in the acknowledgement page submitted to the Land Registration Authority (LRA)," the lawyer told reporters. Cimafranca said they submitted copies of Mrs. Concepcion's passport, showing her departure and arrival in the country from the US during their appearance before the Criminal Investigation and Detective Group—National Capital Region (CIDG-NCR). While the signatories in the sale of the land were residents of San Juan, the notarization was done in Tagaytay City, and the one who notarized the document was not listed in the registry of attorney's of the Integrated Bar of the Philippines (IBP), the lawyer pointed out. Miguel said he learned of the transfer of the ownership of the land to his elder brother upon his return to the country two months ago after retiring from his work in the US. It was learned that a school is presently renting the lot and its buildings. The younger brother of the actor said he tried to reach out with Gabby, yet, he ignored him. "I kept asking him for a meeting to clear things up but he ignored all my request.” "So I'm resorting into this action to correct what is wrong,” he ended. The media tried to reach the actor for comment, but he was not responding.
