In India, is it legal to park your car outside your neighbor's house?

Unless its a no parking zone, he is free to park if the area is empty. If you need to use the area, just make sure that it's occupied the moment he takes the SUV out. You can verify the "no parking" status of the road with the local traffic cops stationed in the area.

Is it blocking your way or causing any trouble at all to you? That could be nuisance, even if you don't own the road outside your house. But if it doesn't block your way or cause any nuisance to you, than your neighbour is free to park it there. Though its absurd why he would choose the road outside your house. Isn't it safer to park the car outside your own home? And why don't you start parking something outside there? Or maybe put some plant pots/vases or something? If you do not have a claim, he doesn't either.

AFAIK he can do it legally but as a matter of courtesy he shouldn't. If you are supposed to use the space outside your home for your purpose, you should be allowed to do it and given preference over it. If he uses this space, you can use his space and eventually he will give up.

if it isnt obstructing anything then what is the problem ? anyway 1) If you have a dog train him to poop outside your neighbors house. or 2) Go to him daily and give complement about his SUV :daily and exact same 3) Encourage your kids to play cricket near that car with leather ball. you can enhance this list by yourself

I face a similar problem with my inconsiderate neighbor, who parks his car in such a way that I can barely take my scooter out.  He parks the car in such a way that I have very little space for ingress and outgress.  Appart from that he parks three scooters perpendicular on the road, thereby causing severe encroachment on my approach road of the society.   Can't how to handle such people.

I think it is not illegal to park your vehicle on the road. But there should be a law. Imagine, if every one who owns a car, parks it on the road, roads will be full of them. If this is the case, the apartment owners need not give covered parking, they save a lot. City traffic police cannot mark every road as "No parking" zone.  You should raise an RTI for this kind of questions. What do you think? I don't know whether these can be raised under that and I also assume that you have the patience to raise an RTI online with the traffic department as you have posted this question on Quora :-)
