Spouse Visa Application Question

[Yazzy]

My cousin has a wife in India and 2 children. 1 child is 16 years old and the other child is 19 years old.
My cousin has owned a house in the Uk for the past 2 years.
He is now selling it and will get £100,000 profit from the selling.

Can he apply for spouse visa as soon as he has the £100,000 in his bank account?
Or does he have to wait 3 months and then he can apply?

Does his wife have to do the English test?
Some one advised him that because he has £100,000 in his bank account his wife does not need to do the English test. Is the correct?
Will his children need to do the English test?

As long as he has proof of ownership of the property he can apply as soon as he has the money.

I don't know anything about the language test, however I do know the money in the bank will make absolutely no difference...

The child who is 19 will only be able to apply as a dependent in exceptional circumstances.
