Rwyf hefyd am ddysgu mwy am y rhesymau dros y cynnydd sylweddol ymddangosiadol yn yr arfer o godi taliadau ystad. I'r perwyl hwn, mae rhannau o'r Cais am Dystiolaeth wedi'u hanelu at ddatblygwyr ac Awdurdodau Lleol y mae eu penderfyniadau yn arwain at greu taliadau o'r fath, yn ogystal â gweithwyr proffesiynol eraill a sefydliadau eraill a all feddu ar ddealltwriaeth o'r defnydd ohonynt.
I also want to learn more about the reasons behind the apparent marked increase in the use of estate charges. To this end, sections of the Call for Evidence are aimed at developers and Local Authorities whose decisions lead to the creation of such charges, as well as other professionals and organisations who may have insight into their use.
