fixing a problem in @adneal answer: if setErrorEnabled is not set true, mErrorView would be null and if you set it false at any point the font would change back to default. so to fix it:

in you custom TextInputLayout override setErrorEnabled

@Override
public void setErrorEnabled(boolean enabled) {

    super.setErrorEnabled(enabled);

    if (enabled) {

        try {

            Field cthf = TextInputLayout.class.getDeclaredField("mErrorView");
            cthf.setAccessible(true);

            TextView error = (TextView) cthf.get(this);

            if (error != null)
                error.setTypeface(tf);


        } catch (Exception e) {

        }
    }
}
