In this paper we describe a computational tool for morphological disambiguation for the Spanish language, designed to be eventually part of a larger grammar checking system for both Spanish and Catalan. This system is based on two different types of tools, namely, a) a low-level morphological parser, and b) a high-level syntactic-semantic parser. At present, we are developing all low-level tools, which, in the mid term, should constitute the basis for a grammar-checking module capable of capturing simple errors in unrestricted text. The rule file contains some 743 rules for morphological ambiguity, which are applied 130.751 times over our development corpus. This corpus, once performed the morphological tagging, has a degree of ambiguity of 64,78%, including both major and minor category ambiguities. After going through the disambiguation process, remaining ambiguities in the corpus amount to just a 13,86%.
