Issue between surviving spouse and heirs on an intestate estate!!! Please I badly need your help.

Good day po. Humihingi po ako ang legal opinion niyo sa sitwasyon namin na mga heirs. My father died almost 3 years now and after his death we filed a intestate estate sa court po namin. Sa hearings po we appointed our mother to be the special administrator. Yesterday, we found out from another person that my mother was trying to loan the property in a financing company without our knowledge and a court order. She said that she will only loan her part of the property ibig niyang sabihin  is ang 50% niya plus ang makukuha pa niya sa equal share niya sa amin as heirs.

These are my questions.
1. Can she really get a loan using her share in the property? Ano po section ng law natin ang nagsasaad nito?

2. If she can loan it and in the future hindi siya makabayad sa ni- loan niya, ano po ang mangyayari sa property na meron po kaming share?

3. In the future at gusto rin namin e loan/ sell yung property, magagawa po ba namin yun?

4. Pag hindi po niya nabayaran ang loan niya, kukunin po ba ng bank/financing/lending company ang whole property?

5. Ano po ba yung magagawa namin para d niya ma loan ang mga intestate estates? Kailangan po ba namin ipaalam sa court/ financing/ lending and banks na these certain titles should not be entertained?

I am really seeking for an advice as soon as possible kasi ginagawan ng paraan ng mother namin kung paano niya ma loan lahat ng intestate estates. Maraming salamat po!

Don't you have a lawyer?
Have your mother sanctioned and her administratorship revoked by filing the necessary motion in the case.
