Create a sample form as follows:

from wtforms import StringField
from wtforms.validators import DataRequired, Length
from wtforms.fields import Label  #<==This is the key

#in forms.py
class MyForm(FlaskForm):
    name = StringField('Your Name', validators=[DataRequired(), Length(min=2, max=20)])
    submit = SubmitField('Sign Up')

#in route.py
from forms import MyForm
#initialize your app

@app.route("/some-test-route", methods = ["GET","POST"])
def someTestRoute():
    form = MyForm
    if some condition:
        #change the label as follows.
        form.name.label = Label(field_id = "name", text = "Your New Field Description Goes Here.")
        #The above line creates the following lable object
        #Your New Field Description Goes Here.
        #which replaces the current label object that is
        #yourname
    if form.validate_on_submit():
        #do something
        return redirect(url_for(endpoint = "someEndPoint"))
    return render_template("WhereEverYour_MyForm_Template.html")
