How to bid 5332 Balance hand when partner bid 1NT?

5332 with slam interest
5 card minor

any system to bid this?

[Yzerman]

Evolution of balanced slam invites include a few corrolaries to the 4NT quantitative invite.  1N-4S becomes 44 in minors balanced asking quantitative and 1NT-4NT is either 4333 or 5332 with 5 card minor.  If opener is to accept they can accept 6NT, bid a suit @ 5 level (this is 4 lowest biddable 4 card suit), bid suit @ 6 level (5 carder) bid 5NT (3334 with 4 clubs) or bid 5C which is acceptance of quantitative bid but ASKING responder what 4 card suit is OR what 5 card suit is.
Responses are;

1N-4N-5C (asking)

5D=4 diamonds
5H=4 hearts
5S=4 spades
5N=4 clubs
6C=5 clubs
6D=5 diamonds

This is how I handle these hands.  Obviously there is a small flaw (perhaps the exact question you would like answered) is how to identify the doubleton in the 5332 hand and judge whether 6m or 6N is in play.

To identify the doubleton is not very easy
but if partner have minimum but you may still have 6 minor when partner have 4 card trump together with a doubleton.

How to any method to due with it?

Acutally I have some idea when I play Hardy 2/1 System's NT bidding

If you utilize MSS this should not be a problem as long as you use good hand evaluation.  With a quantitative raise you may ask MSS if you have a marginal hand but lots of controls or "good cards" (eg  15 or 16 hcp with 5332 and 5 card minor with Qx in your doubleton is generally a wasted value and perhaps only 4NT ask).

Although I like this question, I have not accounted for this hand in my system with my regular partner (unless I forget - LOL).  We utilize many relays after 1NT to ask/illicit/describe information but this hand we have omitted!!!!

My idea in Hardy NT bidding
1N-2C (stayman can have no 4 card Major)
2H-2S (invite to 3NT without 4 card spade or 5332 slam)
->

2N= don't accept invite to 3NT
3C= accept invite to 3NT
3D= accept invite to 3NT with 5 times heart

then respond can bid something to show 5332 invite to slam

2N->
3C = (233)5, 3D future relay for doubleton
-> 3H=3235, 3S=2335, 3N =3325
3D = 3352, 3H = 3235, 3S=2335

3C->
3D =  (233) 5, 3H future relay for doubleton
-> 3S= spade/3N=Heart/4C=diamond
3H =  (23) 5(3), 3S future relay for doubleton
-> 3N= spade/4C=Heart/4D=club
3N = to play 3NT

3D->
3H=3235
3S=3253
3N= to play
4C=(2)3(3)5, 4D relay -> 4H= spade, 4S=diamond
4D=(2)35(3), 4S relay -> 4N=spade, 5C=club
4H= to play

I know is not the best treatment but my approach is simple:  I play 4way transfers so I transfer to the minor, if partner denies interest in the minor we can signoff in game, if partner shows interest then cue-bidding starts and we might find a good slam.
Maybe you can post an example hand to check how this method would have worked (or not)
