Add the following code to your theme’s functions.php file.

Please note that the first checkbox is an Age Confirmation (represened as “age_confirm” in the code) and the other one is Terms Of Use Agreement (represented as “tos_agreement”).

Change the texts in this code snippet according to your needs.

// Add Checkboxes
add_action('woocommerce_after_checkout_billing_form', 'my_required_checkout_fields');
function my_required_checkout_fields()
{
	woocommerce_form_field('age_confirm', array(
		'type' => 'checkbox',
		'class' => array('input-checkbox'),
		'label' => __('I confirm that I am 21 years old or over.'),
		'required' => true,
	), WC()->checkout->get_value('age_confirm'));
	
	
	woocommerce_form_field('tos_agreement', array(
		'type' => 'checkbox',
		'class' => array('input-checkbox'),
		'label' => __('I agree to the terms of use of this website.'),
		'required' => true,
	), WC()->checkout->get_value('tos_agreement'));
	
}


// Process the checkout
add_action('woocommerce_checkout_process', 'my_custom_checkout_fields_process');
function my_custom_checkout_fields_process()
{
	if (!$_POST['age_confirm']) {
		wc_add_notice(__('Please confirm you are 21 years old or over'), 'error');
	}
	
	if (!$_POST['tos_agreement']) {
		wc_add_notice(__('Please agree to the terms of use first'), 'error');
	}
}

//Update the order meta with field values
add_action('woocommerce_checkout_update_order_meta', 'my_custom_checkout_fields_update_order_meta');
function my_custom_checkout_fields_update_order_meta($order_id)
{
	if ($_POST['age_confirm']) {
		update_post_meta($order_id, 'Age Confirm', esc_attr($_POST['age_confirm']));
	}
	if ($_POST['tos_agreement']) {
		update_post_meta($order_id, 'Terms Of Use Agreement', esc_attr($_POST['tos_agreement']));
