I started  in 1975 and in 1976/77 I decided to buy a single storey house for RM 33100 . I took a bank loan of RM 15000 from a bank( and in 1980 I converted the bank loan into a Govt  housing loan) and the balance I  borrowed from some relatives ( in laws) and also my Dad helped me to pay some too.There is however no letter or any trust made to say that I took the money from Dad or any of the relatives.  My father passed away intestate in 1987 . Recently my brother filed a case against me in the KL High Court to apply to become LA for my house  by saying that my father contributed to the house and hence it is Harta Pusaka si mati ( the property is registered under my name) and I held it in trust because dad contributed to it.  He managed to convince my sister and my younger brother to be on his side and support his application.  I had returned part of my dads money by way of contributing for my sisters wedding ( about rm 2000) and once i gave cash to dad also rm 2000. And whenever i visited him I gave rm 50-100 when I had cash with me. Never had dad asked me about the house during my visits to him until he expired. ( 10 yrs from the time i bought the house). I paid for  all dues , maintenance and any costs or the house. Never until today did any of my family stayed or visited me at the said property. Never did they ask about it all these years. ( 1977- 2018)
In the documents that he submitted to the court and me , an exhibit , a letter from Amanah Raya Berhad is enclosed, it says that my father had some money in Malayan Banking and the letter directs Maybank to pay al the money to my brother. There is only one name and no other sibling is mentioned. I never had knowledge or signed any document to forgo my right on this matter. I was never informed on this.
. please advise what are my rights and how shud i go about it. Can the verbal expressions( hujah)  from my sister and brother carry weight against me, because I am alone and they are 3 . I am very worried. I am married and have kids and to face this at this age is very taxing to me and hurts me badly too . I am emotionally breaking down and has caused lot of stress to me, sir.  it further burdens me financially.
I appreciate your advise and thank you so much, Sir.
