Development Laws Prior to 1987 -88

Hi all legal types.

I'm seeking information on a Village which began construction two years prior to the

Land Development Act, B.E. 2543 (2000)

In this time did Developers have to make a deposit into an account for the Village once established and Developer has departed the scene the Village if Juristic retains that deposit for future maintenance?

The only reference prior I have been able to locate is

Land Code Promulgating Act, B.E. 2497 (1954)

Which Law (If Any) applies to a Village which never became Juristic and Developer has only recently (Mar 2017) signed off on Developers License.

I'm am trying to establish is, where does a Sinking Fund Comes from pre 2000 (1997,98)

From my understanding now is New Established Villages create a Sinking Fund by charging several years in advance of Village Fees.  Is this true and any reference would be appreciated.

Cheers

I cant play golf so what else is there to do.
