Although in recent times, oral or triple triple always get challenged in courts. 

2. Stamp or Notarization alone shall not suffice. 

3. There have to be legally valid grounds for talaq. Mehr and maintenance should be settled.

Dear Querist
You may pronounce talaq thrice before two witnesses who also should be Muslims. 
After that send a talaqnama with the mahr amount if unpaid and three months iddat period maintenance and if she is pragnent then the maintenance till her delivery via speed post or register post with acknowledgement. 
It may be on plain paper.  Stàmp is not  required. 

Talaq will be valid. 
Without due procedure of law you can not throw out from your home.

She may file a complaint under section 12 of domestic violence act read with section 17 - 18 / 20 / 22 / 23 of DV act and claim maintenance from you and claim a right to resident in her matrimonial home. Claim compensation. 
She may file a criminal case under section 498A / 406 of ipc against you and your family members for dowry demand and harassment before court or police. 
She may file a maintenance case against you before family court under section 125 of crpc.

It will be better for both of you try to settle the matter amicably with the help of the elders friends and relatives.

In your case, the triple talaq pronounced in the absence of wife will be valid if the same was done in the presence of a qazi and two other witnesses. it can also be on a plain paper, stamp paper is not necessary however it is advisable that you make it on stamp paper. on the basis of the pronouncement made by you, the qazi will have to issue a certificate pronouncing you and your wife to be legally divorced. the certificate issued by the qazi and the plain paper will then be required to be posted to your wife.

These days, such talaq is challenged in the court stating it to be not proper since the mehr and maintenance etc is not settled during that time. the grounds of divorce need to be proved in the court and the alimony be settled. the stridhan be returned.

in sunni muslim personal law no witness is require at the time of talaq( either written or oral) only shia requires 2 witnesses at the time of talaq.  talaq may be given orally. no qazi is require at that time. it can be said before any person and it can be said in any state of mind( in sunni law).
after giving her triple talaq you should convey it any meand that it came in her knowledge. no matters either she accept it or refuse it( in both sunni and shia law). she is liable to obey iddat period and leave matrimonial home. you must pay mehr at the time of talaq and give maintenace  up to iddat period.
she has right to file petition under DV act but she can't claim residential order because it is against the muslim personal law. she can claim maintenance under DV act or under section 125 cr.p.c.
you should not file any cross case against her and be ready to maintain her up to remarriage.
