U cannot teach her lawyer a lesson directly. Just frustrate the lady so that she curses and abuses her lawyer in the lawyer's office and on the phone. She'll also spread the wrong word about service performed and she will withhold the remaining fees.
Also, visit the office of ur opponent's lawyer often to pass on superficial messages to ur opponent through the lawyer: doing this will make ur opponent to suspect their own lawyer. Every time their lawyer fails to answer their call, they will be tormented with misgivings about the lawyer. 498a lady will feel very alone.
The 498a wife should be the real target. If possible, have no income on record and present affidavits from ur loved ones that u owe them money. Show that u r under a lot of debt so that u end-up giving minimum maintenance to her. U should provide proofs of ur ill health, physical or mental or both, which is causing ur unemployment. The biased judge will probably still give her some maintenance. If she is working, u may avoid paying her any maintenance and u may be entitled to maintenance from her whilst the divorce case runs.
If it’s the husband who wanted the divorce and the wife files 498a in a hope that the husband will get scared and will take her back, do not take her back. Never take her back. He should skip the country or just skip town to get away from the unnecessary harassment. He should just think in his head that a nuclear bomb went off and he needs to leave the town. That the town is no more inhabitable for him. She will learn her lesson with no maintenance money, no matrimonial life, and with the wastage of her years. If skipping is not a suitable option, one will need to file cases on her and her family: filing cases r easy if u r economically in a good position or have friends in beneficial places. If u r not well economically, u'll need to work harder on filing counter cases but human mind is ingenious and I have seen often that if an ingenious mind is determined and it's given some time, it will beat out the minds who have more experience in the field or have more means.
If they filed 498a or DV to extract a quick divorce and a quick divorce settlement, do not give them either. To make these kind of ladies suffer, delay the divorce case: do not appear in the divorce case until the exparte evidence date is set: appear on the exparte evidence day with a doctor's note to explain non-appearance on the last hearing and also, ask the case to be referred to the Mediation Centre. Waste months in mediation by leading them on. The written statement should not be filed easily, not for the first 18 months or so (It can be delayed even longer). When the written statement has been delayed to the extreme and when the judge really wants it, then, throw in an HMA 24 application: the settled law is that the judge has no business to force u to turn-in the written statement before HMA 24 is settled. Even if she has filed HMA 24, u r still entitled to file HMA 24 of ur own. Then delay filing the reply to her HMA 24; delay ur HMA 24 argument. Also move in frivolous applications like order 11, rule 12 and act dumb if it's rejected and ask for an adjournment to regroup. Nothing should be done in the case without causing major delays first. Cause delay at every step. On one hearing, to delay the case, u can show papers that u've just applied for legal aid and u r waiting for their decision. And on the next hearing say that the legal aid lawyer was not much good and u want to stick to fighting the case urself. Have no advocate on record in the divorce case and every now and then, just walk into the government hospital on the hearing day with a complain of diarrhea, fatigue, stomach pain etc. and get the note stamped but do not go to Court on that day: make sure the hospital slip has the registration number and then find out on what day the case is set for exparte evidence and show up on that evidence day to present the stamped note. You can repeat this as many times as u like as long as u have no advocate on record: I would recommend to do this every third or fourth hearing: there is nothing the judge can do except give short dates and impose costs. There is another way to cause a major delay in the divorce case but it requires a smooth operator and this should be done near the end of the trial just before the arguments: miss one hearing and get a note from the government hospital for that absence and then be friends with someone who runs a clinic and get urself admitted there a day or two before the exparte evidence and get released a couple of days after the judgment and then move to High Court to reopen the case. Be friends with the High Court staff to get long dates but u must successfully and on record make ur wife aware of the High Court proceedings before she remarries. The High Court will take a couple of years to decide the case and then the case will be sent back to the lower court again as long as ur Hospital certificates r legit. If ur medical notes r legit, no judge, I repeat, no judge has the authority to deny u the benefit of a proper trial. The opposite party, in desperate need of divorce, will drive themselves crazy: the wife’s father will resort to alcohol abuse and the 498a lady will resort to abusing her lawyer. To delay the case, u can move the High Court for a lot of other reasons too. And once a proper divorce is granted in the lower court, appeal in the High Court. After wasting atleast two years or more in the High Court, move to SC. The 498a wife will settle the cases, without the blackmail money, way before u reach the SC. She will have her lost-years as alimony.
