In the HUF property, you and your sister and any other children of your deceased father are coparceners.

Therefore your sister is entitled to a legitimate share in the HUF properties as a right.

If your mother is living then and you are only two children to succeed the HUF properties after your deceased father, then the properties shall be divided into three shares, you shall be entitled to one such share besides your sister and your father's share in the HUF property shall again be divided into three shares in which your mother shall be entitled to one such share along with you and your sibling.  

No doubt the HUF will be dissolved after the partition of HUF properties is effected among the shareholders. 

a) Your sister being a coparcener is entitled to an equal share at par with you in the HUF property.

b) If the property is partitioned then the HUF will be dissolved automatically.

c) you are not the absolute owner of the entire property, if your sister is seeking partition and separate possession of her share in the property then you cannot lease out the property.

d) Once there is a dispute about the share in the property through the claim made by your sister, it would not be possible for you to enjoy the entire proeprty by yourself and you cannot deny or deprive your sister's rights in the property, therefore better you enter into an compromise settlement with her and have an amicable partition instead of having stretched legal battles by which you will stand losing your money, energy and time  because the ultimate result would be that the court will pass a judgment making her entitled to a legitimate share in the proeprty as per law. 

1. She will be a Coparcener and will have equal share. 

2. Not necessarily as now woman can also be karta

3. Yes only with everyone's consent
