Since there is substantial differences in your incomes you can seek maintenance for yourself and children 

2) you cannot claim maintenance for last 12 years 

3) considering his income of Rs 70 K you can seek maintenance for children of Rs 20000 per month 

You can claim for past 12 years two. If you have child you can claim for child also. Generally if wife is employed court is reluctant to give maintenance. But in your case as last 12 years he haven't paid you the maintenance court may grant you. You can try to file maintenance application in family court. You can also file 125 crpc and maintenance under domestic violence Act. 

You and your childrens are entitled to maintenance . The court decides based on the status of the parties.

if you want to rejoin matrimonial knot, then,
try to settle the matter amicably with your husband involving elders/relatives/friends etc and start afresh, and if, failed, file Restitution of conjugal rights petition in the Court,
and,
if you want to terminate the matrimonial knot, then,
try to settle the matter amicably with your husband involving elders/relatives/friends etc and go for Mutual Consent Divorce which will be decided in 6-18 months, and you both will be free to live life with your wish,
don't forget to draft an MOU before approaching Mutual Divorce, which is the most essential and important part of a Divorce case,
some basic points to keep in mind and put in writing through an MOU before filing the petition for mutual consent divorce are custody of kids, distribution of assets (movable/immovable), quash/withdraw of pending litigation if any, Maintenance (present/future), Alimony, mode and time of making the payment, streedhan, future litigation, etc.
if failed, you are advised to file/claim
498a complaint (for causing mental, emotional, physical and monetary abuse, etc)
Domestic Violence case (for causing mental, emotional, physical and monetary abuse, etc)
you have rights to claim residence, protection, compensation, maintenance, etc
if you do not want to opt the divorce presently, you can ask for judicial separation also,

“amount of MAINTENANCE/ALIMONY depends on various factors such as Living Standard, Financial Status, Properties held, assets, responsibilities, custody of children, expenses on marriage etc, therefore, without going through deeply with facts its really unfair to tell an amount. a detailed personal discussion will enable me to answer this promptly"

your mother can be witness in your case . you would be able to prove physical abuse from husband from testimony of witnesses 

You have less income in comparison to his expenditure. You can claim maintenance for you and child. Not of past but from now. 25% of his net income. Since you are also earning, so 15 to 20%.

You can file police complain of domestic voice and rest reliefs you can obtain from court like protection residence order etc.

FIR you can file anywhere. If next time he physically abused you, call on 100% and get medical done. Good proof. Incident of TV will include in FIR

Since you are employed and earning a handsome salary you may not be eligible for maintenance amount from  him, however you can claim maintenance for your child.

He i responsible to maintain the household expenses despite the fact that you are employed and earning an income.

If you want to get separated then you can apply for divorce on mutual consent grounds, if he is not agreeing for divorce then you may file a contested divorce on the grounds of cruelty.

Since he is not earning and the income he is getting is from his father's business or other income, he will simply state that he has no income hence he my not be able to pay any maintenance to the child.

Therefore you can file a suit seeking injunction against his properties, if any , from alienating it or encumbering it in any manner for the purpose of providing security towards the maintenance for your child.

It may not be necessary to produce documentary evidence to prove his acts of cruelty, you can make the same in the pleadings and can make your mother as a witness and any other person who would be willing to give evidence in your favor in the divorce case.

You can discuss with an advocate in the local and proceed on the advises received.

you can claim as he is earning far more than you. For that you will have to file petition u/s 124 of crpc for maintenance. A wife has all the rights to live a standard life the way her husband is leading but you cannot claim maintenance for 12 years 

1. Even an earning wife can claim maintenance from her husband if her income is insufficient for her to meet her needs.

2. You can claim anything. It is for the court to award a quantum which is just.

3. Irrespective of the income earned by wife, husband is bound to maintain his child. Maintenance of children is a joint responsibility of both parents.

1. No it is not true, he is liable to pay maintenance if he is earning more than you, but court may not grant maintenance to you but your child will definitely get maintenance for him.

2. You should file case for domestic violence against your husband in this suit you will get compensation for physical assault suffered by you and maintenance as well as residential orders along with custody of child. 

3. You should also file maintenance suit on behalf of your son. 

Legal expenses depend on number of proceedings initiated by you. You need to produce all evidence during proceedings to prove your case

You have to produce what ever evidence you have at once, should not with hold the same.  The same will play a vital role in taking decision by the court.

As far as witness of your neighbours, if at lease one of them come and give evidence it will certainly have positinig bearing on your case.

He is earning so he should spend on you and his son. He cannot deny this. File a maintenance application and the court will grant you some amount in addition to what you are earning.

The court shall grant you alimony and maintenance if you decide to get separated. 

As his property belongs to his father that can be a problem as he may say taht he doesn't earn anything. Also file a domestic violence case against him based on the evidence you have.
