it can be a big hassle, see your local town offices.

there are minimum lot size rules, fees for sub dividing, rules about
sewers or they will require you get the entire parcel perk tested for
septic rules about curb cuts, the list can be endless, depending on
where exactly the property is.

All this costs big bucks, a good friend did it and had to post a 11
grand bond to cover the cost of a future serer line to serve the sub
divided parcel.

you will almost certinally need a lawyer to get this all done perfect.

good luck you will need it.

my in laws bought 3 lots in a subdivision, all have irregular shapes to
meet perk test rules...
