<?php
// Variable for post ID

// Query the relationship
	$relpa = new WP_Query(array('post_type'=>'page','posts_per_page'=>'-1','post_parent'=>'6',
		'meta_query'=>array(
			array(
				'key' => 'rel_attorney', // This is the custom field's name
				'value' => "$pID", // This is the post ID of the current page you're on
				'compare' => 'LIKE'
			)
		))
	);

  // Check if there are any relationships
	if($relpa->found_posts){ ?>
	<h2 class="rel-title">Practice Areas</h2>
	<ul class="rel-list">
	<?php }
  
  // The loop
	while ( $relpa->have_posts() ) : $relpa->the_post(); ?>
		<li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
  <?php endwhile;
  
  // Check if there are any relationships (this is done again to close out the ul)
	if($relpa->found_posts){ ?>
	</ul>
  <?php
	} // Close the check if there are any relationships if statement
  
	wp_reset_postdata(); // Reset the post
