Must the fiancée inform her suitor about the burn marks on her body before the marriage contract?

If the burn scar is significant and disfiguring, such that it is likely to cause the husband to be repulsed, then he must be informed before the marriage contract; because concealing it is deception and fraud. However, if the scar is not very prominent or does not cause repulsion, then there is no obligation to inform him of it. In cases where informing is obligatory, it should be done through the father or the brother.
