Legal Question in Criminal Law in Washington

By financial relief, I presume you mean attorney's fees and costs. If you are pro se, the answer is generally no, except for costs (e.g. service fees). If you are represented, the answer would be yes, if the petition was filed without reasonable basis (exactly what a reasonable basis would be is something that can be defined with precision only in the context of the case and a judge/commissioner would have to be asked to make a determination on it).
