Halacha Bal Teacher

Halacha – bal te’acher
Rambam (Hilchos Pesulei ha'Mukdashim 14:13): It is a Mitzvas Aseh to fulfill Nedarim, Nedavos and other obligations to pay Erchin, Damim, Ma'aseros and Matanos Aniyim at the first Regel. We learn from "U'Vosa Shamah; Va'Haveisem Shamah". When you come to Yerushalayim for the Regel, you must bring all your obligations. If he did not bring his obligation at the time of the Regel, he was Mevatel the Aseh. If three Regalim passed and he did not offer the Korbanos or pay the money he transgressed "Lo Se'acher Leshalmo". There are no lashed for this for there is no action.
